dmesg

Getting this occasionally while zooming windows or moving graphic objects
(drawing etc).  It happens too rarely to be reproducible, but often enough to
be annoying.  The hang somehow makes X restart after repeated reset attempts.

[54034.511500] [drm] GPU HANG: ecode 9:0:0x85dffffb, in Xorg [836], reason:
Hang on render ring, action: reset
[54034.511509] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[54034.511513] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[54034.511517] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[54034.511520] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
