Comment 1 Martin Peres 2018-04-17 13:00:02 UTC 
This reduces the coverage in CI massively (like https://bugs.freedesktop.org/show_bug.cgi?id=106103), so bumping the priority!

Comment 5 Lakshmi 2018-08-29 11:08:15 UTC 
This issue was not seen since last 6 rounds from drmtip execution, need to wait at least 4 more rounds to see no failures are occurred. Then we can consider this bug to be closed.
Comment 6 Martin Peres 2018-11-01 15:59:11 UTC 
Used to happen every run, now not seen since drmtip_88 (3 months, 2 weeks / 47 runs ago). Closing!
