The GPU crash dump

[  129.612656] [drm] stuck on render ring
[  129.612903] [drm] GPU HANG: ecode 9:0:0x85dfbfff, in compiz [1579], reason:
Ring hung, action: reset
[  129.612905] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[  129.612907] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[  129.612908] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[  129.612909] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
