<pre>A number of test failures have been observed when running
ES2-CTS.functional.fragment_ops.blend.* tests on IVB with the 4.13 kernel.
Setting INTEL_DEBUG=reemit (again, on 4.13) causes these tests to pass
consistently.
In order to reproduce this, we had to loop these tests and run multiple loops
at the same time on the system. It took a handful of iterations for the failure
to happen.
These failures do not occur when the kernel version is rolled back to 4.9. No
other hardware platforms were tested.</pre>
