--- Comment #1 from Chris Wilson <chris at chris-wilson.co.uk> ---
Interesting to note that both tests failed with the blitter. No hang, and
breadcrumb write must have succeeded, but an equivalent STORE_DWORD to the user
buffer did not. Still suspect TLB or the aliasing PD?, just a pity it didn't
hang.
