[gentoo-mips] PANIC: Unexpected exception at boot o2 R5000

[gentoo-mips] PANIC: Unexpected exception at boot o2 R5000

[Andrew Finley]

Hello All,
I am trying to install on a O2 r5000.  After what I thought was a
successful kernel build, etc. (following the install instruction on the
MIPS project page, and using the experimental livecd).  I powered off
then tried to boot, then received the message below.

> boot -f vmlinux
2125824+167632 entry: 0x881d2040

PANIC: Unexpected exception

[Press reset or ENTER to restart.]

I'm not sure what you might need from the error so I just copied the
beginning and end down.

I double checked my steps an am not sure what is going on.  Does anyone
have any ideas?  I would really really appreciate any help you could
offer.

O2 can't boot off disk directly (that is, load a kernel from the volume header 
like IP22).  You have to use arcboot for that.  Arcboot's a hair slow at 
reading kernels off disk, but wesolows made a wicked patch I'm going to test 
soon and put into portage which will dramatically speed up disk loading.

Just `emerge arcboot`, and follow the instructions printed after the build 
finishes, and things should work out fine.  If not, drop a note here about it.

[Andrew Finley]

Hi Kumba,
thanks for the note back and all your work getting me this far. I'm a
bit slow, so let me get this straight, I had the livecd and followed all
the directions (e.g., did a stage 2, and built the kernel then put it in
the volume header), then had the boot off the main disk problem.  So now
should I do the following?

steps:
1) put the live cd back in and boot off of it, then chroot
2) emerge arcboot
3) once the arcboot is done compiling it will print some directions on
how to boot the kernel from the main disk header?

Is this right? 

Also, I followed the kernel specs for the Indigo2/Indy, is that still ok
for the o2?

Thanks again for your help, I really look forward to getting this
machine up and running again, if it works we have 6 more 02s' in queue.

Indy/Indigo2 systems are known as ip22, whereas O2 is ip32.  It is 
almost a completely different arch aside from the processor, so if you 
compiled a kernel for ip22, then arcboot won't even save you here.

If you want a kernel that is known to work for O2, check out 
http://dev.gentoo.org/~geoman/vmlinux64-2004-11-06.bz2 for now.  It will 
let you boot your system do stuff until you are able to build a proper 
kernel.

It's advised you give the "Portage Introduction" a quick readover at this URL:
http://www.gentoo.org/doc/en/handbook/handbook-mips.xml?part=2&chap=1

(The mips bits of the handbook are very outdated, so don't fully expect other 
mips bits there to work, we need a docs dev that can help get things 
straightened out).

It's a little unfair to throw some users new to gentoo right into the 
experimental stuff sometimes, but that's the nature of O2 units right now, as 
well as some of the other mips hardware.  I'll probably stable-mark arcboot in 
a few days to clear up some of the confusion, and eventually put one of the 
2.6 mips-sources stable (2.6.9 is unstable now).

[gentoo-mips] arcboot problem R5000 o2

[Andrew Finley]

Ok, I tried.

On the R5000 O2:
1) emerged arcboot, then following the man page, I put it in the volume
header.

2) ignored the boot partition I made during the system install, and made
a file called kernel in sda3 (i.e., my root partition see fstab below)

3) I put the kernel that Steve gave me into the kernel file

4) changed the arcboot.conf to reflect my changes (see below).

5) then back to prom I did "boot -f arcboot" - result was an error
something like "can't find kernel looking in \unix"

I tried several variation on this theme but with no luck. What am I
doing wrong?
Thanks again.

Why not just use sda2 if you already have it designated for /boot?  You 
just have to make sure that arcboot.conf goes into /boot/etc.  Also 
remember you have to set SystemPartition to the volume header from the prom.

Re: [gentoo-mips] arcboot problem R5000 o2

[Andrew Finley]

Hi Steve,
Ok I moved the kernel and /etc/arcboot.conf to my /boot (and as noted in
the man page, made a link from boot to boot) and changed my arcboot.conf
to reflect the changes.

Now in the prom I resetenv so that:
SystemPartition = pci(0)scsi(0)disk(1)rdisk(0)partition(8)

then ran arcboot - then it says it can't find the arcboot.conf or an
ext2fs.  Then it says to adjust OSLoadPartition to
pci(0)scsi(0)disk(1)rdisk(0)partition(2)  Which I tried with no success
I also tried pci(0)scsi(0)disk(1)rdisk(0)partition(1) with no success.
My boot partition is on sda1, root is sda3, and swap is sda2.

any ideas what I'm doing dumb?

You shouldn't *have* to adjust OSLoadPartition actually.  Arcboot 
auto-detects that.  You did mount /dev/sda1 on /boot *before* you 
copied the config file and made the symlink didn't you?

In any case, I have the same configuration you do in terms of partition 
layout (with the exception of sdb1 mounted on /usr), and it WorksForMe(TM).

Your Good Steve,
I did forget to mount boot the last time.  And got it to boot, part
way.  I got a "kernel panic - not syncing: No init found. Try passing
init= option to the kernel" 

Sorry to keep bugging you, but I'm not sure where to find help (google
only works so far) :-)

Well, that's interesting.  It seems that both the kernel looks at 
OSLoadPartition from the prom when being loaded via arcboot.  Arcboot 
uses OSLoadPartition to determine where the kernel and arcboot.conf are 
stored, and it uses the SGI naming scheme to do so (eg the 
pci(0)scsi(0)disk(1)rdisk(0)partition(X) bit).  The kernel uses 
OSLoadPartition to determine the root device, and apparently the 
append="root=/dev/sda3" from arcboot.conf isn't getting passed, or is 
being overridden.  Try changing OSLoadPartition to /dev/sda3 from the 
prom.  Arcboot will spit an error that you should change it to something 
else, but then will scan the other partitions for /etc/arcboot.conf and 
should auto-detect what partition it really needs and then boot normally.

[gentoo-mips] R5000 o2 X11 and kde?

[Andrew Finley]

Hi Steve,
I went back through and double checked everything, rebooted, and
resetenv, and presto, arcboot booted properly.  Now we're cooking!

Then tried to emerge X-org, which compiled fine but could not build a
config file.  I looked for some documentation on the gentoo mips site
but didn't see much (and elsewhere).  Is it possible to get X and
eventually kde running?  Thanks again for your help.

I've got x.org running on my o2. I used geomans config that you can find 
here: http://dev.gentoo.org/~geoman/xorg.conf

Make sure that you compiled x.org with the static-useflag enabled. 
Otherwise it's likely that you'll get a bunch of unresolved symbols.

Have fun!

See Ian's message about the config file and building X with the static 
USE flag.  As for kde, it should work just fine, although it may take 
two to three days to build it all.

Hi Guys,
Thanks for the help, X build just fine and gdm looks o-so-nice.  I tried

How do I get around this? 

Should I get around this? 

Do I need to put something in my /etc/portage/package.unmask?

With with all my questions, you made a mini-howto for dummies:-)

I have not seen this even once with my kernel.  Perhaps you have a 
really old prom version that is doing something funky, but I just don't 
know.  You didn't try to do something funky with objcopy to change the 
address or something did you?

This is a known problem.  The O2 rtc has been broken since 2.6.9 
somehow.  I've talked to somebody that said they haven't seen this 
problem at all.  I'm wondering if it is a result of a) the gentoo 
toolchain or b) a patch I'm using.

Also, my kernel wasn't compiled with module support at all...in fact, I 
think mine is 2.6.10-rc2.  I know why you are getting the error (kernel 
looking to autoload rtc module probably), but I don't know why it is 
looking for the module at all.

Not sure what the deal is here without more information, but it isn't 
fatal.  You probably have some service set up to start which isn't 
installed or is broken.  Check your boot logs.

Gentoo most certainly doesn't require devfs.  Our stages ship with a 
static /dev directory.  You can boot with "gentoo=nodevfs" to avoid an 
annoying error about devfs on boot.  However, what is even better is 
udev.  Just "emerge udev" and boot a 2.6 kernel...and Gentoo's init 
scripts take care of the rest.

You really should learn to build your own kernel anyway.  I would 
recommend the latest mips-sources-2.6.9 ebuild instead of being thrown 
into the fire right away with checking cvs out and tracking down the 
right patches.  You can't just use the standard kernel.org tarball for 
mips machines really.  You should also stop by our irc channel 
(#gentoo-mips, irc.freenode.net) sometime if you haven't already.

[Andrew Finley]

Hi Steve, 
thanks again for the fast response. udev worked real slick.  

I realized my system clock was set to ~1953 (perhaps this has some thing
to do with the mysterious crashes).

I will read up on cross-compiling over the holiday and give my own
kernel build a shot.

-have a good one

Re: [gentoo-mips] PANIC: Unexpected exception at boot o2 R5000

[Andrew Finley]

Thanks Steve,
Ok, should this kernel go in the volume header then use arcboot?  If I
wanted to build a proper kernel, can I still use the kernel that comes from
emerge-source (if so what build options should be used)?

Arcboot loads from the volume header, but it doesn't boot kernels out of 
a volume header at all.  Rather, it boots them from an ext2/ext3 
partition.  So, you would put arcboot in the volume header, and then the 
kernel on and ext3 or ext3 partition, set up the config file, and then 
just do "boot -f arcboot" from the prom to get going.  If you happened 
to do something silly like make your entire filesystem reiserfs or xfs, 
then you are out of luck with respect to arcboot.

As for building your own ip32 kernel, you have to use 2.6 sources, which 
you will have to unmask yourself.  You can run "make ip32_defconfig" 
inside the source tree, which will give you a base config to work from. 
  You can then enter menuconfig and tweak to your liking.  Or, you could 
get my config from /proc/config.gz when/if you are able to boot my 
kernel, and then tweak that.  In any case, you can't use the native 
system compiler, since the kernel must be 64-bit.  You will either have 
to emerge gcc-mips64 (after making sure you are using the proper 
cascaded profile), or build a mips64 cross-compiler on another machine.

Sweet, looks like building my own kernel is out of the question in the near
future. Fortunately, my boot and root are ext2 and ext3 respectfully, so
perhaps this will still have a happy ending.  I'll give it all a whirl with
your kernel tomorrow.  Thanks for your patience.  Have a good turkey day.
