--- Comment #8 from Ilia Mirkin <imirkin at alum.mit.edu> ---
OK, well staring at the code didn't do me much good.

bkref == NULL means that the pushbuf thing doesn't know about the bo we're
trying to reloc. However just a few lines above in nv30_transfer_rect_m2mf we
do

nouveau_pushbuf_refn (push, refs, 2)

which should tell it about the src/dst bo's. So either there's concurrency
going on, or something's not working as advertised. In the no-concurrency case,
I'd need repro steps (that can't start with "install tons of software").
