<pre>From the error-state, I would say it just takes stress, you just need to hit
the right timing between CS interrupt and ELSP submission. If that is the case,
igt should be able to trigger it indirectly.
My assumption may well be off, but I would start with just running
texture-gather-offset (or which ever piglit got caught in that GPU hang) in a
loop; probably with a background "find / -type f -exec cat {} \;"</pre>
