[12576.077100] [drm] GPU HANG: ecode 7:0:0x85ffbffa, in et.x86 [14043], reason: Ring hung, action: reset
[12576.077101] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[12576.077101] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[12576.077102] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[12576.077102] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
