[ 2148.621070] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 2148.621071] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 2148.621072] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 2148.621073] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.

I am running non-vanilla linux kernel 3.15.2, with other patches applied
(tuxonice, uksm, bfs, bfq). This happened after resuming from hibernation
(several attempts). After restarting X, everything seems to work fine.

Other symptoms: Sometimes after resuming from hibernation there is a pink
horizontal line pattern on parts of the screen (on half of the screen or
sometimes only over the xfce panel,...).
