Also G94 here, and the same bug. It works for a while then GPU locks up with
"still angry after 101 spins". But, I bisected and eventually 19a10828814aa
commit (drm/nouveau/fifo/g84-: ack non-stall interrupt before handling it) came
out as culprit. It's the last nouveau commit before 3.18 was releases.

If you can compile your own kernel, I'm attaching the patch that reverses that
commit. It fixes the issue for me completely, no more lockups.
