general protection fault: 0000 during resume

[Matt Zimmerman]

This happened while I was trying to diagnose bug 328035 by starting up a second X server and then executing a suspend/resume cycle.

After the fault, the system was unusable (X never came back up and the text consoles were corrupted) and had to be rebooted.

[Andy Whitcroft (apw)]

@Matt -- could you attach an X log file for this machine, /var/log/Xorg.0.log so we can see which extensions it is loading. Thanks.

I just saw this happen again. I had (apparently successfully) resumed from S3 and was starting to work in my session (I started a download of updates) when I noticed that mutt segfaulted. dmesg showed a series of oopses starting with the one below. Only this one was successfully logged, and the system quickly became unusable and had to be power cycled.

[Rocko (rockorequin)]

I get something like this frequently while doing a shutdown cycle with the 2.6.28 kernel, including up to 2.6.28-11-generic#37 amd64.

The symptoms are:

1. I choose restart or shutdown.

2. The usplash screen shows and shutdown seems to progress normally.

3. Near the end, the screen changes and either goes blank or it shows the end of a fault message.

4. If I control-alt-delete, it continues shutdown and restarts.

The log might show something like the attached.

I used to think it was something to do with the nvidia module, because it seemed to always do this if I did a suspend/resume cycle and then tried to reboot, but not if I just rebooted without a suspend/resume cycle; then I added nvidia to the list of modules to remove by adding it to /etc/pm/config.d/modules and for a while this seemed to fix things. It isn't working any more though.

Currently, it does it with all of the nvidia 180.37, 180.41, and 185.13 drivers.

[Rocko (rockorequin)]

Here's Xorg.0.log.

By the way, suspend/resume does work properly on this PC (usually at least - sometimes though X restarts on resume). It's the shutdown that is crashing. It would be a big problem if I was trying to reboot remotely.

[Ben Prescott (ben.prescott)]

I couldn't find many hits at all for this issue.

I'm not getting much apart from the dump; no 'general protection fault'. But since I upgraded a machine to 9.04 and piled on a bunch of upgrades and additions, every time I've shut down the gnome session has ended, screens gone blank, system beeps, and hangs. I can't get to a virtual terminal. Numlock still responded, so I concluded it was a UI problem.

I can ssh in from another system and interact in a limited fashion; 'ps' hangs. init 0 does nothing; poweroff -f worked the first time, but not the second.

I'm running the nvidia driver offered by ubuntu.

[Ben Prescott (ben.prescott)]

ps. appreciate I've matched my issue with this issue based on limited evidence - system is still up, Nvidia, attempted power cycle, release of Ubuntu, and a error which is a similar shape to mine. I've not seen one of these traces before, and am clueless about interpreting it. I guess the kernel spat it out, but I wouldn't know how to find documentation for it. If you can see I'm in the wrong place, please help me understand why!

[Ben Prescott (ben.prescott)]

"usplash," I deduce, refers to the process that triggered the issue, and I think this is the wrong thread for this issue.

for the benefit if anyone who finds their way here with the same issue as myself, the tactical fix to my problem appears to be to remove the pretty boot up sequence (and configure the console for my screen resolution) - removing the references to 'quiet' and 'splash' and replacing with, say, vga=0x307

about /boot/grub/menu.lst changes: http://ubuntuforums.org/showthread.php?t=542082
about vga=: http://tinyurl.com/5ff36

this doesn't fix the underlying issue, whether in usplash or elsewhere.
