Comment 2 Jari Tahvanainen 2017-01-20 08:41:10 UTC
Mika - is there some commit submitted that has resolved the issue? In latest CI executions verdicts for tests mentioned in comment 2 are either pass or skip. See https://intel-gfx-ci.01.org/CI/fi-ilk-650.html.
Comment 3 Mika Kuoppala 2017-02-17 13:46:19 UTC
We haven't seen this in at least the past 100 CI runs. There was lot of work in this area q4 of last year so something in there have made a difference. Finding the exact commit tho would be worksome.
