[ 764.492100] [drm] stuck on render ring
[ 764.493303] [drm] GPU HANG: ecode 8:0:0x85dffffb, in X [2336], reason: Ring
hung, action: reset
[ 764.493307] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 764.493310] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 764.493312] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 764.493315] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
