Comment 1 Chris Wilson 2018-08-16 07:37:05 UTC

The appearance and disappearance coincided with it being hit by the rpm wakeref leak; so presumably not just a coincidence.

Comment 2 Chris Wilson 2018-08-16 20:22:12 UTC

Assuming it was a stray rpm wakeref leak, those should now be resolved.

Comment 3 Martin Peres 2018-09-03 11:31:37 UTC

Still happening:

This issue has not been observed in nearly 6 months now. Earlier it was seen every week on GLK and SKL machine every week.
