------------------------
When running cts runner on SKL somewhat "random" tests fail. I am still
gathering data on this issue, but so far:

The number of failing tests on a full cts-runner run are equal to getting a
new:

"[66951.923100] [drm] stuck on render ring
[66951.923838] [drm] GPU HANG: ecode 9:0:0x85dfffff, in cts-runner [14838],
reason: Ring hung, action: reset
[66951.926772] drm/i915: Resetting chip after gpu hang
[66953.923521] [drm] RC6 on"

in dmesg.

The tests appear to fail on random configs. To check the result of the
cts-runner I use the scripts/

So far after 4 runs I have only see these test fail on respective config:
