[29404.084979] [drm] GPU HANG: ecode 7:0:0x85dffff8, in krunner [1214], reason:
Ring hung, action: reset
[29404.084981] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[29404.084982] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[29404.084984] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[29404.084985] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
