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).
