I occasionally get the following message:

Nov 12 20:40:34 xxx kernel: [drm] GPU HANG: ecode 6:-1:0x00000000, reason:
Kicking stuck semaphore on render ring, action: continue
Nov 12 20:40:34 xxx kernel: [drm] GPU hangs can indicate a bug anywhere in the
entire gfx stack, including userspace.
Nov 12 20:40:34 xxx kernel: [drm] Please file a _new_ bug report on
bugs.freedesktop.org against DRI -> DRM/Intel
Nov 12 20:40:34 xxx kernel: [drm] drm/i915 developers can then reassign to the
right component if it's not a kernel issue.
