[13419.609879] [drm] stuck on render ring
[13419.610453] [drm] GPU HANG: ecode 7:0:0x85fffff8, in kwin_x11 [1081],
reason: Ring hung, action: reset
[13419.610454] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[13419.610455] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[13419.610456] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[13419.610457] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
