Comment 3 Chris Wilson 2017-10-06 21:18:33 UTC

Fwiw, this is the same coherency issue as bug 100587. The testcase just demonstrates that another piece of uABI that assumed perfect coherency is susceptible.

Comment 4 Martin Peres 2017-10-19 10:36:48 UTC

Marking as duplicate as to Chris' comment (which I agree with).

*** This bug has been marked as a duplicate of bug 100587 ***

This tests continue failing on GLK QA
