Comment 6 for bug 1391086

I can repro this consistently by installing Hearthstone on Windows 7, and trying to run the game. The repro is rather bulky. FWIW, at least the bits can be obtained gratis (Win7 has a trial, Hearthstone is free to play).

The kernel log is filled with these messages:

[ 1167.316496] nouveau E[ PFIFO][0000:01:00.0] PBDMA0: ch 11 [VBoxCrWinCmd[6069]] subc 0 mthd 0x000c data 0x20030298
[ 1167.316510] nouveau E[ PFIFO][0000:01:00.0] PBDMA0: METHOD

The bug appears to be very similar to the following Ubuntu bug, which has more debugging information:

Please let me know if I can supply extra information to help debug this.
