Created attachment 57477 [details] extract from syslog Hey, I have an issue with my Intel GM965 card (on Thinkpad T61, running Debian sid). Basically when letting my screensaver (which is glsideshow displaying pictures on both LVDS and VGA screen) run for too long, the GPU seems to hang. I experienced it few times when I forgot to close the laptop lid for the night, when waking up the displays are black, no answer when touching the keyboard, but the laptop is still alive and can be accessed by ssh. There, I have the attached logs (dmesg and syslog) I have debugfs mounted so I can show some debugging information if you tell me what you want.

Feb 21 22:05:19 hidalgo kernel: [236215.660109] [drm] capturing error event; look for more information in /debug/dri/0/i915_error_state Please attach the error-state :)
Created attachment 57481 [details] error state Here it is.
Nothing appears obviously wrong. :|
That might be because the problem appeared last night or early this morning, but I got the error state this evening. I've rebooted the laptop and will let it idle tonight, and see if it happens again. Then I'll provide the new error state.
The error-state looks genuine, I just can't spot an actual error. If it does happen again, please do attach further error-states and lets hope the bug is more obvious in one of those, or a pattern becomes evident.
Created attachment 57505 [details] new log So it did happen again, so here's a new log.
Created attachment 57506 [details] erro state And the new error state. Unfortunately I forgot to mount debugfs *before* it happened, so it might be invalid.
Can you also post an Xorg.log following one of the hangs? There's a slim chance it contains some warnings from before the hang.
The error state itself demonstrates the same hang, so it is consistent even if I have no clue as to the cause. The shotgun debugging response would be to run with sna (download xf86-video-intel.git and ./configure --enable-sna) to see if that makes any difference.

I'll try to do that (first by using the same build options as the Debian package just to be sure, then with sna).
I've upgraded to 2.18 with SNA enabled and will report back
So I tried 2.18 with and without SNA: with SNA, problem seems fixed, without it still happens.
Yves-Alexis please keep using SNA for the time being, and please do report any issues found. Thanks.
