<pre>This is an i915 test and shouldn't be affected at all by nouveau. Also
[ 22.762957] [drm] Simulated gpu hang, resetting stop_rings
so this isn't actually a bug, but just an issue with our debug output being a
bit too noisy.
Now this noisy error output to dmesg was added in
commit 05407ff889ceebe383aa5907219f86582ef96b72

drm/i915: detect hang using per ring hangcheck_score
Why was that not caught as a regression? Or have I missed the bug report?
I'll write a quick patch to tune down the debug output.</pre>
