[ 395.268190] [drm] GPU HANG: ecode 6:0:0xf4e9fffe, in Xorg [1327], reason:
Ring hung, action: reset
[ 395.268191] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 395.268192] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 395.268192] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 395.268193] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[ 395.268194] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[ 395.268311] [drm:i915_set_reset_status [i915]] *ERROR* gpu hanging too fast,
banning!
