[43728.912443] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[43728.912444] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[43728.912445] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[43728.912446] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[43728.912448] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
