I'm using mesa git master. Sometimes openarena (exec anholt) finishes OK with
just the warnings (tons of them), occasionally it hangs with the last message.
The hang appears to happen more often on nouveau master than vanilla 3.12
The card is:
[   10.238807] nouveau  [  DEVICE][0000:01:00.0] Chipset: GF119 (NVD9)
[   10.238809] nouveau  [  DEVICE][0000:01:00.0] Family : NVD0
couple with snb intel.

the bug is perfectly reproducable, let me know what other info I can provide.
