[126770.012985] [drm] stuck on render ring
[126770.013842] [drm] GPU HANG: ecode 6:0:0x87e8fffd, in MediaPl~back #1
[93854], reason: Ring hung, action: reset
[126770.013844] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[126770.013845] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[126770.013847] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[126770.013848] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
