I believe this is fixed by this patch:

Updated the kernel to the latest revision which contains the patch and have run
piglit test three time and no oops this time. So I'm closing as unreproducible
with latest code.

The correct resolution would be FIXED, as it's a reproducible bug fixed by the
patch.
