Comment 2 Chris Wilson 2019-04-05 07:43:32 UTC 
That casts aspersions on the HW.
Comment 3 Francesco Balestrieri 2019-04-08 10:05:07 UTC 
As Chris says above, we suspect pre-prod HW flakyness to be the culprit. If it will happen consistently it could be a more serious issue, but the only way to know is wait and see.
Comment 4 Francesco Balestrieri 2019-04-08 10:47:15 UTC 
Meanwhile, I suggest that we lower the priority to max "high", or just live with the fact that you are not going to get daily updates on this one :)

Agree with you. Setting it high priority.
Comment 7 Jani Saarinen 2019-04-22 12:18:17 UTC 
Still seen only once.
