Description Mark Janes 2015-09-28 17:25:14 UTC 
When SSBO support was pushed to master, the following piglit test fails intermittently on broadwell:

piglit.spec.arb_shader_storage_buffer_object.array-ssbo-binding

> bin/arb_shader_storage_buffer_object-array-ssbo-binding -auto -fbo
piglit: debug: Requested an OpenGL 3.2 Core Context, and received a matching 3.3 context

Wrong 0 value in buffer[1]: 0.00

Since the test is intermittent, I will disable it in Intels CI system for bdw.

FWIW, Samuel Iglesias Gonsálvez introduced this test, but posted the following to the piglit list:

    We don't have any Broadwell machine. However we can help you with the
    debugging, don't hesitate to contact Iago or me.

    Thanks,

    Sam

Additional testing shows that this test fails about 60% of the time on BDW.  If igalia has no BDW machine to reproduce it, then this bug should be assigned to someone who can reproduce it.

retesting this bug with a new kernel, I find it to be reliable.
