Description Mark Janes 2015-12-11 19:33:27 UTC 
This test fails intermittently, and is likely associated with d04612b60d98ff785646affaffc3d7243deecb74 when compute shaders were enabled.

It was first reproduced on IVBGT2, and also seen on HSWGT2 and HSWGT1.

piglit.spec.arb_shader_image_load_store.qualifiers also fails intermittently, first appearing on bdwgt2.

I'll disable the tests in the CI, and track resolution with this bug.
Comment 1 Mark Janes 2015-12-11 19:51:18 UTC 
The ivb system that this test failed on was booted with i915.enable_cmd_parser=0, which may affect the test execution.
Comment 2 Eduardo Lima Mitev 2016-02-25 11:41:55 UTC 
Are these intermittent failures still occurring?

I have tried reproducing this and it passes 100% of the times, for at least 10k tries. I have mesa trunk (as of today, git~439b5b0), kernel 4.4.2, and tested on HSWGT2.

Mark, is it possible to give these tests a chance in the CI and see if this is still valid?
Comment 3 Mark Janes 2016-02-26 20:18:07 UTC 
works for me now.
