[ 1959.241685] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[ 1959.241686] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 1959.241687] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 1959.241688] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 1959.241689] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
