I have the same problem, are able to reproduce it and have bisected it, but the commit which git --bisect identified seems not to be the cause.

Note that Guennadi is running kernel 3.5 which does not contain that patch - generally there are billions of ways to hang your gpu, so every gpu hang needs it's own bug (until we've analyzed the error_state and triaged the bug taking other evidence into account). Also, this is on a different gpu generation, so even more likely that it's a different kind of hang.
Thanks, Daniel
