[gentoo-user] Epic list of total FAIL.

[gentoo-user] Epic list of total FAIL.

[Alan Grimes]

My five year old CPU has been working it's ass off the last few days
doing a full --emptytree world to try to purge the system of the ncurses
clusterfuck.

Here is the list of FAIL. A few of these might be stale listings because
I didn't purge the directory before running this. Also a few of these
might work if I tried it again because a document generator was in
ncurses-fail mode when it attempted to build the relevant package. One
of these, however, was OMFGROTFLMFAO funny... You'll see what I mean
below. What does it say about the state of linux when the compiler is
too broken to compile a bug reporter module? =P

I usually tolerate a moderate failure %-age but these packages are far
too important to the things I need to do to be acceptable. =|

[Alan McKinnon]

Let me describe what I see.

This can't be a clusterfuck, as it is affecting only you. No-one else to
my knowledge is reporting problems caused by ncurses.

So, it is then highly likely that you have a setup that the devs did not
consider, and it is rare (if not unique).

So, what exactly did you do to fuck your system up this badly? Don;t say
"I ran emerge world" as lots of other people do that without issue.
Before that, perhaps long ago, what did YOU do that caused this current
issue?

Ranting on the list might make you feel better, but is not likely to fix
your problem. Just saying.

In fact, the more you rant and swear and insult people, the fewer
people are going to pay attention and try to help.

Don't worry, in his previous thread, named with the insightful subject
"!!!!", the OP just didn't care to reply after several people chimed
in to help, so I doubt that fixing the problem is what the OP really
wants.

Here is a quote from the other thread, just to set the tone:

Seeing segfaults in a compile like that makes me question your hardware
rather than the gentoo tools.  Are you sure your hardware is in a
functional state?  I update my world fairly often and am running ~amd64 and
have not experienced the issue you are experiencing. :(

The ncurses ebuild is indeed broken, I ran into the same problem before.

But you received good advice on your last thread (build libtinfo on another 
system and copy it or just try symlinking it to ncurses), if you'd followed it 
you would a got your system back up in a few minutes.

Good luck,

ppl seem to be antsy to hear what I actually did, so I'll respond....

1. I got my grubby mitts on a stage 3 tarball, I always keep one on hand

2. I grepped everything in /bin and /lib for tinfo and copied over from
the tarball where necessary.

3. Started --emptytree world.

4. waited.

5. kicked it each time it stopped,

6. kicked it some more.

7. kicked it a few more times.

8, got to the end of the list about two and a half days later (which is
par for my machine.)

9. published the results.

10. rebooted.

Because we try to avoid flame wars and needless name-calling/swearing
when looking for and providing support to people. Also because we kind
of expect the original poster to respond to queries in a thread that
they started.

This is kind of dangerous. It would be safer to create/use a binary
package.

- From a running Gentoo system (including a stage3) you can create a
binary package of an installed program by running

  quickpkg <category>/<package>

This will place it in /usr/portage/packages by default (see PKGDIR in
`man make.conf`). This is better than just randomly copying files from
another system. There are also online hosts available that provide
some packages (see my post in your previous thread).

Emerge's '--keep-going' option may be of use to you here...

So what you're saying is that you did an '--emptytree' build for which
there were a number of failures; *one* of which was a segfault; some
of which may not be valid; after arbitrarily copying some files from a
stage3 of unknown age.

Don't get me wrong, providing feedback and letting others know is
good, but unless there's a baseline and/or more is known about what is
going on (see Alan McKinnon's comment about others not getting this
and something about your environment potentially causing this), we
can't do much with it.

More information about your environment, such as an `emerge --info`
and relevant flags/settings for a specific package that is failing
would go a fair way to giving us the information we need (and have
asked for) to be able to help you.

C{XX}FLAGS="-O3" is known to cause some issues [1]. If you've done an
- --emptytree rebuild with "-O3" then this could be the cause of the
segfaults.

The `emerge --info` helps, but you haven't listed an explicit build
failure or details about that package.

Earlier I saw segfaults in gcc, and another poster pointed it out.

When gcc segfaults, it is always suspicious mostly because the compiler
is an app where we know the devs take extraordinary measures to prevent it.

The most common cause is faulty hardware (most often memory) as gcc
tends to use all of it in ways no other app does. The usual procedure at
this point is to run memtest for an extended period - say 48 hours, or
even 72 for an older slow machine.

That is definitely good advice.  I've run into this situation several
times.  A machine had bad RAM that didn't seem to cause any problems
under "normal" operation.  But, when trying to compile something large
like gcc, I would see non-repeatable segfaults (it wouldn't always
segfault at the exact same point).  In those cases, I could often run
memtest for several passes and not see an error. But, _eventually_
ramtest would catch it.  Run memtest for a few days.  Really.

Yeah, I know there's a single bit error out at the end of RAM that will
appear on the third or fourth pass...

Idiot.

Of _course_ software expects memory to work.  Why don't you stop
bothering us and go write an OS that doesn't depend on RAM working
properly.

I built my first machine nearly a quarter century ago. =|

That said, I spent the day doing diagnostics:


Findings:

1. There were a hell of a lot more memory errors than I had seen before.
2. There was a smudge on one of the dimm's contacts and some of the
usual dust on the CPU-facing one.
3. The motherboard was not developed by sane engineers. In a sane world,
there are two types of variables: measured variables and controlled
variables.
The RAM voltage would appear to be a controlled variable but it is also
a measured variable. In order to achieve a close approximation of 1.5v,
I had to set it to 1.530 volts. WTF...

4. an AMD K10 processor cannot successfully drive 8-ranks of high
density ram at 2x800 mhz -- BUT IT WILL TRY!!! I found all dimms to be
good either individually or in pairs, but the entire ram compliment of
four dims cannot be run at full speed at once with the CPU/motherboard I
have installed.

5. I found a set of settings that went through memtest fine but caused
linux to segfault and die. I backed off the FSB a few notches while
adjusting the multipliers to stay within the specified frequency for the
processor and it seems to be OK now.

Findings 3 & 4 sound like a faulty or underrated PSU...or a bad motherboard. 
Start by unplugging everything that you don't need to boot from a live CD and 
run some tests.

It sure does.  A weak power supply will certainly cause some issues.  If
he can remove a few power hogs and it works, then the memory may be OK
and just short on power.  Plus, if the power supply is weak, that could
show up in other places too.

I also concur that the most likely cause of this problem is the PSU but first, 
I would clean the RAM contacts.  

Then try a replacement PSU if you have a spare one, or take your multimeter 
and measure the output, checking for lower voltage values and fluctuations.  
If you get bad measurements, then take your soldering iron out and for a few 
pence inspect and replace any domed, or all capacitors on the secondary 
(output) side.

<nitpick>
A multimeter is not really a valid test. If say the 5V rail is dodgy,
then the output will still be a solid 5V. What's happening is that the
PSU regulator circuitry can't keep up so the output averages 5V (that's
what the transformer gives out) with large amounts of high-frequency
ripple superimposed. Your multimeter average's that out and displays ...
5V! When things get really bad the output may dip momentarily when load
is drawn, but by that stage the PSU has been struggling for a long time
already.

Use an oscilloscope instead, and you see immediately what condition the
output is in.
</nitpick>

Few IT techs just happen to have an expensive oscilloscope just lying
around, so a good recommendation is to replace the PSU anyway every 2
years or so - more if the thing runs hot. I consider these as wearing
items, sorta like oil filters

Valid nitpick, esp. if an oscilloscope is available.  Anecdotally, I have seen 
the amplitude of the ripple almost double *after* a repair than before.  
Admittedly, I think I used a capacitor with higher voltage rating, because 
that's all I could find at the time. Nevertheless, the PC worked fine after 
the repair, because the voltage output was at the right value and would hold 
steady under load.  BTW, I've seen voltage values look reasonable when not 
connected to a load and collapse when load is applied.

Yes, most electrolytic capacitors 'wear out' as time passes and drift from 
their original tolerance, which is quite wide to start with.  I have repaired 
half a dozen of PSUs over the years with good results and unless I have a 
spare PSU available I resort to replacing the capacitors.

It used to be the case that PSUs with (Japanese made) Hitachi caps could be 
relied upon for a build, but I don't know what comes out of China today.

Re: [gentoo-user] Re: Epic list of total FAIL.

The PSU is an Antec EarthWatts 750.

Biggest hoggs outside the motherboard are the, um, er, well [nvidia 980
gpu] and an aging Western Digital Velociraptor boot drive. There is also
a 3TB drive for all my p***, er kerbals   ( Kerbal Space Program ) .
There is one optical drive and four chassis fans in the system. All fans
are operating perfectly.

As far as I know the operating conditions for the PSU are nearly ideal....

I did have some noise issues with it a few years ago but it seemed to
settle down and hasn't really given me any grief since.

Maybe you should assume less and test more.

This is good advice, replace the power supply despite your thoughts.
They *are* the cost common failure item.

That noise could be what the problem was.  Just a example.  A fan's
bearings starts making noise.  Eventually, the bearings lock up and the
noise stops.  Guess what, the fan has stopped too.  Of course, the noise
is gone now but that doesn't mean the problem is gone does it?  Odds
are, some component was making noise because it was under pressure or
age was catching up or whatever.  When the noise stopped, it had likely
stopped working at all.  This sounds like a capacitor to me.  They will
make weird noises sometimes before they fail.  I used to work on TVs a
lot years ago, you know, the old tube type stuff.  Anyway, those caps
did all sorts of weird things.  Some would swell up until they were
shaped like a hot air balloon or something.  Some would blow out the
bottom and maybe even stink real bad.  I've even seen some that blew the
metal can completely off and the TV is full of that sticky paper stuff,
which also stinks, and the foil part.  Some just smoke and make a
hissing sound, then all heck breaks out in the TV.  Usually it stops
filtering and the rest of the TV is now getting a unfiltered DC which is
about like A/C.  Some components like those tubes don't like that much. 
They tend to revolt.  FET type components, when they go, they usually go
quick, with a bit of stink or smoke.  Usually. 

Yea, I'd be looking for a new power supply.  Some of those on that last
link I posted aren't that expensive.  Just calculate up what power you
need.  I tend to add at least 50% to that, for future expansion and
start up power.  Doubling it wouldn't hurt.  It just means your P/S is
running at half power most of the time.  On my current P/S, it is a 650
watt unit.  According to my UPS, my entire computer system pulls about
150 watts idle and about 160 to 170 when compiling the crap out of
something like GCC, Libreoffice etc.  Now that includes my monitor,
router, modem and speakers.  If I were to guess, the puter itself only
pulls around 100 to 120 watts.  My power supply has some overkill issues
for sure.  I could likely easily use a 300 watt unit but would likely
replace with a 400 watt since they are more available.  Technically, I
could use a 200 watt if the power supply was a well built model. 

As it is, my power supply likely never even gets warm.  Add in that it
is in a Cooler Master HAF-932 case and I'm sure the fan gets bored.  The
key thing on power supplies.  If you are going to buy cheap, buy big. 
Cheapos tend to overrate themselves, sometimes a LOT.  If you buy a well
known and well tested brand, it will likely deliver what it claims and
you can pick closer to your actual ratings.  Of course, that cheapo P/S
will likely fail you at some point.  That means risking losing a lot
more than just the P/S too.  It could mean a new CPU, mobo, memory and
whatever else it takes with it.  When cutting costs, protection is one
place to do it and by the time you realize it, it's to late.  I've
bought cases with P/Ss built in.  They get removed and disassembled for
little junky projects.  I mostly get heat sinks and such since most of
the components aren't reliable anyway. 

Hope you get this fixed soon.

Which may be a good idea, since then it’d be running at optimum efficiency.

Getting OT here:
Didn’t you say (waay back) that you run AMD? Because in that case those
numbers don’t add up (they also don’t for a medium-range intel). 120 W @
idle (which in itself is a lot) and then only 30-ish more for full CPU load?

If only such models were actually available. The lowest value you can get in
a reasonable-quality build is 300 W, which is far too much for silent, small
home PCs for simple usess like office or media centre. Such mini systems
barely reach 20 W. Even at full load they won’t get past 60 or 70 W. This is
just at the start of the 80+ efficiency range wich begins at 20%.

Yep.  I would not buy a P/S that didn't have at least 30 or 40% of
headroom.  If nothing else, as the P/S ages, it wouldn't be so stressed
on those older components.  Also, I would only do that if I know I won't
ever add to that rig.  I usually aim for half load or even a little
less.  I almost always end up adding something or upgrading something
before I retire a system.

I got those numbers from the UPS.  Just for giggles, I disconnected my
A/C, plugged the UPS into that plug and measured them with a clamp on
meter at the breaker box.  Doing the math, I got about the same numbers
as the UPS gives me.  The difference might run a night light, maybe. 
The most I have ever seen this system pull is about 200 watts.  I think
I was printing and doing some updates at the same time.  I remember
thinking about that being the biggest load I ever seen.   Oh, my A/C is
on a dedicated circuit.  Nothing else is on that line.  The plug the UPS
usually plugs into only has my TV and some lights on it. 

From the UPS and confirmed by a clamp on meter just in the past few
minutes. 

Idle:  146 watts
Load, well into a gcc compile with all four cores running at close to
100% and drive activity:  186 watts

Keep in mind, my A/C is off and it's warming up here.  If I listen
close, I can tell the fans are spinning a bit faster.  Of course, it's
hard to hear those huge fans.  That HAF-932 is quiet but still moves a
lot of air.

That was my point.  Most P/Ss that are that size or smaller than that
are either old or junky made.  Basically, something I would not buy or
recommend.  Finding a quality P/S that is 350 or less would be
difficult.  I don't recall seeing any in a long while, not that I have
actually tried to find one tho. 

Keep in mind, I didn't build this system to be green.  When I first
built this thing, I figured it would pull at least double what it
actually does if not much more.  My old rig pulled about 400 watts I
think and it is nothing compared to the speed this rig has.  While
having more processing power, it sure doesn't use more energy.

You know those multi terabyte hard drives they make, every bit of those
platters that are actively in use must work perfectly.  If just one
thing, just one tiny bit, is not working correctly, you get bad data. 
With computers, one bit of bad data means something doesn't work be it
hard drives or memory or even the CPU.  You may can live with it on
widoze but not Linux.  Linus maximizes the use of memory more so than
windoze.   I have 16Gbs of ram here.  Even if I don't compile anything,
eventually all my memory will be used by cache if nothing else.  Once
that cache hits a bad spot, there is trouble.

Might I also add, whoever told you to live with it, I hope they don't
work on airplanes and I wouldn't take advice from them to much on puter
stuff in the future. 

Just my $0.02 worth.

LOL. It's perfectly reasonable.
If it's under warranty, return it. And get a different brand cause it sounds 
like what you got is crap.

If it's not under warranty and after running the test for an extended period 
as adviced you're sure that it's only a single bad bit at the highest end you 
can boot with the mem= option. Also see memmap and memtest.

You can not blindly mix and match files like that, this is likely what broke 
your compiler (if you copied only some gcc related files)! You where advised to 
copy the bash binary, or libtinfo.so (from another system), or symlink it to 
libncurses.so. All good advice but you chose to do something dumb. Now you may 
need to unpack a whole stage3, start over, and wait another 3 days.

Hello Alan Grimes,


You seem to imply you are running hardware less that some version
of the latest 4/8 processor monster?

Perhaps something lighter then the kde5 for the QT family, there is
lxqt(1.0) Fairly young but very fast even on older hardware. It's using
QT5 so if you are 'qt centric' in your needs, then you might just
like lxqt as many others do.


O3
I also saw that option. On older systems, I often find that Os runs
very fast, as the smaller size of the resulting binaries allows
ram to function more appropriately. 

hth,
James
