[25527.071252] [drm] GPU HANG: ecode 8:0:0x000c2b2a, reason: Ring hung, action:
reset
[25527.071256] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[25527.071258] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[25527.071261] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[25527.071263] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
