(Get the code!)
The underlying problem here is that the GPU is locked up. Nouveau doesn't have the same sort of GPU hang detection that Intel (or Radeon, for that matter) have, so what happens is that any time something tries to touch the card it never gets a reply. After a while, X notices, and you get a EQ overflow.
Nouveau has no way of resetting the card, so it's going to remain locked up until you restart.
Upstream is looking at reverse-engineering a processor on the newer nouveau GPUs which they believe to be behind this instability.
Until they've got that done, it might be worth quirking off acceleration on these cards.
