Comment 1 Francesco Balestrieri 2018-11-23 10:40:15 UTC 
Is the assignment to display/audio correct?
Comment 2 Francesco Balestrieri 2018-11-23 10:53:33 UTC 
Seen once so far. Maybe not "highest"?
Comment 3 Lakshmi 2018-11-29 07:50:48 UTC 
This failure occurred only once CI_DRM_5127 (2 weeks, 2 days / 480 runs ago).
Setting the priority to Medium. I doubt if this is our bug.

Also, this could be same as https://bugs.freedesktop.org/show_bug.cgi?id=107918

Historically all the bugs related to this failure are closed as Notourbug.
