That's expected to fail as bxt is not as coherent as we advertised.

Good to know, but this means this bug will stay open forever then. Are we OK with that?

Can we instead accept a certain amount of failures for this test for BXT, so as we can catch more dramatic regressions?

Comment 3 Chris Wilson 2017-08-07 09:35:10 UTC

It's an expected failure for a certain class of machines. There is no mechanism within igt to mark those up, so we rely on filtering the results.

Comment 4 Jani Saarinen 2017-09-01 08:13:09 UTC

Lets drop priority as seen yet only once:
failure rate of 1 / 96 runs (1 %)
