With which tests before? So far, it seems like we could only reproduce this bug once in 83 runs[1]. I would need to check on the pre-merge results to see if this bug has been caught there, but it gives you an idea that you will need to execute IGT way more often than once to actually catch this bug. But seriously, no need to try to reproduce [BAT] bug reports, we have all the data possible for developers to act on this.

Thank you for the information Martin. Some history facts:https://intel-gfx-ci.01.org/cibuglog/index.html%3Faction_failures_history=181.html Here is history data: https://intel-gfx-ci.01.org/cibuglog/index.html%3Faction_failures_history=181.html Moving high since being sporadic: CI_DRM_3011: 2017-08-28 / 114 runs ago, with result 'incomplete', failure rate of 2 / 300 runs (1 %) AH. One month gone. Lets resolve. |
