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.
