Created attachment 128404 [details] Dump of the GPU hang When I woke up my laptop from suspension rarely I get a gpu hang. Just to give an approximative idea about the frequency, maybe this happen once every fifty suspensions. The dmesg says: [28377.998735] [drm] stuck on blitter ring [28377.999292] [drm] GPU HANG: ecode 8:2:0xc9835ff6, in Xorg [697], reason: Ring hung, action: reset [28377.999294] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace. [28377.999295] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel [28377.999296] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue. [28377.999297] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.

Please test with latest version of kernel and Mesa (12 or 13) and mark as REOPENED if you can reproduce and RESOLVED/* if you cannot reproduce. Moreover, can you attach xorg log and confirm your content from /etc/X11/xorg.conf.d/20-modesetting.conf ? You may try either: - update your version of xf86-video-intel (https://cgit.freedesktop.org/xorg/driver/xf86-video-intel/) - use glamor to see if this resolve your issue: in /etc/X11/xorg.conf.d/20-modesetting.conf, set the following Section "Device" Identifier "Intel Graphics" Driver "modesetting" Option "AccelMethod" "glamor" Option "DRI" "3" Option "Backlight" "intel_backlight" EndSection
(Note this error state is a kernel bug.)
I can't update my kernel due to another bug (not related to the graphic drivers) and I can't reporduce the problem because it happens rarely. I'll try your suggestions, thank you.
Note that this is not a strict dup of bug 99632, but it happens to be an early bug in the long line of hibernate bugs. *** This bug has been marked as a duplicate of bug 99632 ***
