            Bug ID: 109549
           Summary: [ICL]
                    piglit.spec.arb_compute_shader.render-and-compute GPU
                    hang under load
           Product: Mesa
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/i965
          Assignee: anuj.phogat at gmail.com

This test passes reliably by itself.

However, if you run the test while the piglit suite is running, it will quickly
generate a gpu hang.

To reproduce:  in one window, execute the test in a loop:

  $ for ((;;)) do arb_compute_shader-render-and-compute -auto -fbo; done

Run `dmesg -w` to watch for gpu hangs

In a second window, run piglit.  GPU Hang will be produced within a few tests.
