--- Comment #4 from Ilia Mirkin <imirkin at alum.mit.edu> ---
Ah, interesting. This is a different 8400 GS than I thought (marketing names
are so misleading). That PCRYPT=0 thing will do nothing useful. But.... it
might still be the same issue I thought it might be, just not as visible in
kernel messages.

Can you grab a copy of envytools (https://github.com/envytools/envytools) build
it, and run

nvapeek 1540
nvapeek 154c

and report back with the results of those commands? (You can do this while on
blob drivers as well as nouveau, doesn't matter.) Additionally, try booting
with nouveau.config=PCE0=0 in the kernel cmdline and see if that fixes your
issues. (That should cause it to use M2MF instead of COPY for buffer copies.)
