[i915gm] computer freezes some time after resume

[David Tombs]

My Xubuntu 9.10 computer freezes at some arbitrary time /after/ I resume from suspend. Reproduction steps:

1) Boot up, log in.
2) Suspend.
3) Resume.
4) Continue working, will eventually freeze with no CAPS flash.

Haven't tested if it will still freeze while idle or freeze at the console, will try further testing later today.

This didn't happen until a couple months ago, but unfortunately I don't have any old kernels installed to test those.

I forgot to mention, this bug report is from after a suspend/resume but (of course) before it froze. Note scary-looking error messages in dmesg immediately after suspend.

[Charlie Kravetz (cjkgeek)]

For resume from Hibernate failures, please include the output from the following commands from the boot following the hibernate, this includes information on the search for the resume device etc:

   1. cat /proc/cmdline
   2. cat /etc/initramfs-tools/conf.d/resume
   3. Is your /home encrypted?

[David Tombs (dgtombs)]

Thanks for the reply, Charlie. Note that this is resume from suspend and not from hibernate. But here's the output you asked for:

1. cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-2.6.31-19-generic root=UUID=c58b489c-69be-4673-8e55-0776e96924ad ro quiet splash

2. cat /etc/initramfs-tools/conf.d/resume
RESUME=UUID=ce66e3dd-e15e-46e0-8cdf-94eb5a1d9c67

3. Is your /home encrypted?
Nope.

Also, I tried to reproduce outside of X (from a VT) but couldn't. Of course, this doesn't guarantee anything, but I'm tempted to think it's an X-related bug especially because of those errors in dmesg about my video card.

[Charlie Kravetz (cjkgeek)]

Thanks for reporting this bug and any supporting documentation. Since this bug has enough information provided for a developer to begin work, I'm going to mark it as confirmed and let them handle it from here. Thanks for taking the time to make Ubuntu better and supplying all the logs and data!

I can confirm this on both karmic and lucid. Computer never freezes before suspend and always freezes some time after. If computer was running long before suspend, it usually freezes quickly after resume. If I do suspend resume immediately after boot, computer lasts more, sometimes several hours. Xorg seems to be culprit there any way to downgrade Intel driver to jaunty verion?

[David Tombs (dgtombs)]

Dmesg seems to indicate it's a kernel driver issue, perhaps we could try a mainline build. I will when I have a good opportunity.

[ogc (hackrez)]

I am testing mainline 2.6.34-020634rc5-generic #020634rc5 SMP Tue Apr 20 10:07:04 UTC 2010 i686 GNU/Linux
and after about 20 hours uptime and no less than five suspend resume cycles everything still works. But lucid uses 32.11 so I will test that also.

[David Tombs (dgtombs)]

I can reproduce with mainline equivalent of my kernel (linux-image-2.6.31-02063109-generic) so the bug does not appear to be in an Ubuntu patch (if it's in the kernel at all).

[David Tombs (dgtombs)]

Actually, I can ssh into the machine and do normal stuff after the freeze, so I believe it's an X bug. Updating package assignment.

Ancient freeze, countless many fixed since, presuming this is one of them.
