I also get the "Xid 13 + GPU has fallen off the bus + PC locks up" bug with nvidia v304.32. Has there been any progress in tracking down this bug?
Bumblebee found that rapid polling could cause a "GPU has fallen off the bus" crash as well (https://github.com/Bumblebee-Project...bee/issues/201
). Might this be relevant? fwiw, I still experience the crash even if I make bumblebee use blocking sockets.
