Description Evgeni Golov 2009-07-22 00:37:19 UTC
Hi, I have a ThinkPad X300 here, with a GM965 inside. Running kernel 184.108.40.206 (and 2.6.31-rc3), xf86-video-intel 2.8.0, xorg 1.6.2. Ah, and its all x86_64 here, Debian Sid. When I have KMS enabled, about 50% of my resumes from hibernate (disk) end up absolutely fubar: X is there, I can move the mouse, type, the running apps run fine, but new ones segfault right after the start (or die with an assertion error). As soon I disable KMS, I can't reproduce this behaviour anymore. Not sure this really belongs to xorg/intel, and not to drm/intel or kernel/intel, but I hope there is someone who can push me in the right direction (esp wrt getting useful debug information here).

After some more testing, it looks more like a kernel issue here. Previously I suspended with "pm-suspend" which uses uswsusp if its there, and plain old kernel suspend if its not. I tried both with the same results, but both from X. Now I disabled X, rebooted, and just did a plain echo disk > /sys/power/state and got the very same segfaults after resume.

Hi, Evgeni Thanks for the test. From the description it seems that this is a kernel bug rather than intel graphics bug. Will you please open a new bug in kernel bugzilla? Thanks.

As this is a kernel bug rather than intel graphics driver bug, this bug will be rejected and marked as "NOTOURBUG". Thanks.
