[ 3687.336359] [drm] stuck on render ring
[ 3687.336371] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[ 3687.336375] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 3687.336378] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 3687.336382] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 3687.336385] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
