--- Comment #20 from Marcin Slusarz <marcin.slusarz at gmail.com> ---
I talked to Ben about this bug at XDC2012 and he told me we are using
nv04-style virtual memory interface, because of some then unknown bugs in nv4x
implementation - and this is probably the reason why you are seeing this bug.

Since XDC, Ben fixed and enabled nv4x-style virtual memory in nouveau.git, so
please test it!
