Well, we can't just go around breaking stuff deliberately for the people still using them!
I've blacklisted them myself and merged the patch.
Ben,
This patch causes my dual-head Quadro FX570 (G84) to fail to idle when dragging a window around.
It loops for the full timeout (15 sec.) in nouveau_gem_ioctl_cpu_prep() -- ie., never reaches required fence sequence #.
FWIW, I can get the binary 319.32 driver to run this hardware with MSIs on [1] and not crash in similar circumstances.
But repeating the testing on 3.12.0-rc2/3 has proved challenging. Although I have the binary driver running on 3.12.0-rc2, the userspace won't fully come up and I haven't figured out why (it's an old userspace that I don't use regularly, so it could be some other problem).
Regards, Peter Hurley
