Hi,

[210312.019592] [drm] stuck on render ring
[210312.020688] [drm] GPU HANG: ecode 8:0:0x85dffffb, in valley_x64 [18217],
reason: Ring hung, action: reset
[210312.020690] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[210312.020691] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[210312.020692] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[210312.020693] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
