[gentoo-user] Shutting down process hangs - how to proceed?

[gentoo-user] Shutting down process hangs - how to proceed?

[meino.cramer]

Hi,

 I am updateing my Gentoo on a dialy basis.
 Since two days the shutdown process of the systems 
 hangs around "Bringing down net.lo".
 Booting the PC is not a problem -- except the
 "replaying transactions" (resierfs).

 I fear to finally damage the filesystem while trying
 to figure out, why the shutdown process does not
 succeed.

 How can I proceed?
 What is suspicous for hanging the shutdown process?
 Every help is very welcome !  :)

 Thank you very much in advance!
 Keep hacking!

I don't know about the reason it hangs but this may help get you a
cleaner shutdown.  This is taken from a email that was sent to me during
that horrible xorg-server and hal upgrade.

I tried this once when I was unable to get my keyboard to respond to
anything else.  I made it through the first three or four and was
returned to a console with a working keyboard.  Since you are shutting
down, you may want to go through them all to be safe.  I think the last
one does a reboot.

Hope that helps.

Hi Dale,

thanks a lot for your help!!!  :)

This will help to bring donw the machine in an more
cleaner way as simply pressing the power switch ;-)

But:
How can I figure out, what hangs the shutdown process itsself?

Keep hacking!

That will be answered by another guru who knows what to ask.  I have
never had mine to hang like that so I have no idea.  Someone will be
along soon and help that knows how to figure this out or has ran into
this before.

Last time I came across a problem like this I had forgotten to select the 
right chipset under Graphics support/AGP Support/ in the kernel.  So I 
suggest you revisit your kernel and xorg drivers setups for your card.

Hi,
I got a similar problem too once... and what was making the system
hang wasn't the last shutting down thing listed, but the one just
after (so i don't think it's net.lo fault in your case). So i suggest
to have a look at which services are started at boot, but aren't
shutted down. Turning off parallel boot could help you find out the
responsible service.
In my case it was a misconfiguration of the alsa module, which
shouldn't be unloaded at shotdown time...

 Hi Davide,

 Is there any way to figure out, in which sequence what is shut down 
 *without* actually shutting down ther system?

 Have a nice weekend! :)

I'm sure there's a simple way of finding that out but I was wondering if
this might be your problem?:

Hi Peter,

I scanned the bugzilla entry...as far as I understood unloading of
snd_hda_intel hangs due to an unclear dependency.
I am running my Gentoo on an Asus AV8 board with Via chipset and
AMD CPU, so "no intel".

Nonetheless I added the UNLOAD_ON_STOP="no" to /etc/conf.d/alsasound
and we will see what happens.
All this works for a long long time...and it bits me about three days
ago. I did not update alsa*, since I use the kernels alsa-stuff and
the according lib/utils/etc. of the portage tree.

Fingers crossed...

Thanks for your help !:)

Have a nice weekend!

mcc

If that doesn't work, then exit your X session and Ctl+Alt+F1 will drop you to 
a console.  Run '/etc/init.d/xdm stop' (or gdm if you are running gnome) and 
then zap.  Then '/sbin/shutdown -h now' from the console.  If it hangs again 
the problem is not related to your video card kernel settings.

HTH.

Did you try stopping the alsa service manually?

This gave me errors, since my Webcam's audio part isn't implemented as
full audio device, but it does not hang:

solfire:/home/mccramer>sudo /etc/init.d/alsasound stop

Ah! I've seen that same error when I neurotically switch back and forth
between different kernel versions (cf. autoflagellation).

Try (as root) 'alsactl store' and see if that makes any difference.

It produces a comparable error, since it does a comparable thing...:

alsactl: get_control:249: Cannot read control '2,0,0,Mic Capture Volume,0': Invalid argument

...but this "problem" was there long before the system cannot be
shutdown anymore and I think it is not clean but the root of all
evil....

Well, in any case you should be able to eliminate those error messages
if you delete /etc/asound.* and then repeat the alsactl store.

I also have /etc/asound.names, which was apparently created a year ago
by "alsactl names" (now deprecated).  If you have that file it should
also be deleted.

If alsactl is deprecated -- what to use instead?

Sorry, only the "names" flag is deprecated, not alsactl.

Thanks for the explanation!

What about trying to stop every single service by hand and see if one hangs?
you can have a list of services by "rc-update show" (or something like
that, not really sure)
and then "/etc/init.d/<servicename> stop" for every service, leaving
the boot ones for last

Hm.  Does alsamixer show that guilty control?

I ran strace on alsactl and it consults a very small number of files
while doing a 'store' operation, so there are very few places that
Mic Capture control could be hiding.  You might try using strace to
see what turns up. (If the error bothers you, of course.)

Hi.  I have a somewhat similar problem, when I shutdown it goes all the
way to the end, but instead of shutting down, it says
init: nomore processes left in this runlevel.  This is fine if I am
here, but from a remote location it would not work, so how can I figure
out why this is happening?  I think this started when I went to
baselayout 2, but not certain of that.

I solved the problem:

/etc/slim.conf has the 

    daemon = no

flag, so the boot process seems optically ok but hangs right
after slim hast started.
Shutting down the system tries to stop services/processes/action,
which never has been started...which fails in a hang.

I dont know exactly...but...if that flag is the default configuration
when installing slim I would suggest to change it to

    daemon = yes

to prevent users like me to spend the weekend in searching for a 
problem in the shutdown process.

I don't have such a file, or as far as I know, such a package.  My
shutdown does not hang, it just says no more processes left at this run
level and sits there forever and will not restart the system.

Has the OP checked his inittab file?  I ran into something like this
once a long time ago and I had to replace the inittab file since some of
it was gone.  That file belongs to sysvinit so it may be worth
re-emerging that to see if helps. 

I can post mine if you want something to compare to.  Off list of
course.  Then again, it may not be to big.

Other than this section, I didn't see any differences.  Surely that
wouldn't cause this type of problem. 

I'm clueless.  emerge -ev system maybe?  It may catch something that is
broken.

I also thought of the alsa problem pk mentioned. But it might also be another 
kernel module. Search your /var/log/messages or dmesg for kernel oopses.

I scanned dmesg output and the log files before and found nothing. May
those parts were victim of the "replay transaction" while rebooting
the system afterwards...
