[ 103.764101] [drm] GPU HANG: ecode 7:0:0x87df7c12, in Xorg [1199], reason:
Ring hung, action: reset
[ 103.764103] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 103.764103] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 103.764104] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 103.764104] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[ 103.764105] [drm] GPU crash dump saved to /sys/class/drm/card0/error
