--- Comment #2 from Chris Wilson <chris at chris-wilson.co.uk> ---
It's only prime_vgem, right? That's the one that tries to interleave
read/writes to and from GTT. Ah, probably because gem_mmap_gtt/coherency only
checked the one direction (a fault of writing the test for the known bug
instead of thinking about possible variants).
