[621699.944514] [drm] stuck on render ring
[621699.944525] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[621699.944528] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[621699.944530] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[621699.944533] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[621699.944535] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
