--- Comment #5 from Chris Wilson <chris at chris-wilson.co.uk> ---
Ok, so the extended soak tests only show the issue in the uc-before testcases.
The theory here is that the CPU is doing speculative prefetches from before the
call to execbuf/sync. (Or at least that is what this test was intended to
detect, and since none of the others fail, it seems reasonable to assume it is
this effect.)

So looks like nothing to see here, an expected failure.
