239726.963055] [drm] stuck on render ring
[239726.967006] [drm] GPU HANG: ecode 8:0:0x85dffffb, in valley_x64 [8637],
reason: Ring hung, action: reset
[239726.967015] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[239726.967016] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[239726.967017] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[239726.967018] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[239726.967019] [drm] GPU crash dump saved to /sys/class/drm/card0/error
