Comment 7 Marta Löfstedt 2017-10-13 12:38:55 UTC

The fix was integrated in CI_DRM_3228, the issue is not reproduced. However, I would like to see results from a couple of more runs before I call it verified.

Comment 8 Jani Saarinen 2017-10-13 13:11:35 UTC

Lets resolve as patches are merged.
But follow will be done and only after few runs will be verified

Comment 9 Marta Löfstedt 2017-10-16 06:02:55 UTC

The issue has not been seen since CI_DRM_3228.
