Description Mark Janes 2016-06-07 17:11:16 UTC
deqp-gles31.functional.synchronization.inter_call.without_memory_barrier.ssbo_atomic_counter_mixed_dispatch_100_calls_1k_invocations began failing recently:

The first sighting was with Mesa 2b648ec, but that commit is likely not the culprit, due to the intermittent nature of the failure.
Comment 1 Mark Janes 2016-06-07 18:32:20 UTC
bisected to 

b1f22c6 * i965: Enable cross-thread constants and compact local IDs for hsw+
Comment 2 Mark Janes 2016-06-07 20:40:25 UTC
This failure has now also been seen on hsw.
Comment 3 Mark Janes 2016-06-13 15:16:25 UTC
This failure is also seen on SKL and BYT, although it reproduces less readily.
Comment 4 Jordan Justen 2016-06-24 03:39:18 UTC
We think this is actually a test bug:

https://code.google.com/p/android/issues/detail?id=214108

Should we exclude the test in Jenkins for now?
Comment 5 Mark Janes 2016-06-24 13:33:15 UTC
This test is disabled in CI.
