[ 642.930715] [drm] GPU HANG: ecode 8:1:0x5ccddf92, in gem_exec_suspen [6045],
reason: Engine(s) hung, action: reset
[ 642.930921] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 642.930925] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 642.930929] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 642.930932] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[ 642.930935] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[ 642.938079] [drm:i915_set_reset_status [i915]] *ERROR* gpu hanging too fast,
banning!
S3 and S4 works fine without issuing batch commands to the GPU.</pre>
