310.14 driver crash

Using 310.14 with a 560 GTX on Ubuntu 12.04 LTS, drivers obtained via Ubuntu’s hardware drivers tool. X crashed and the GPU fan was on at 100% capacity. Here is the relevant syslog:

I wasn’t doing anything at the time, the computer was idle.

I’ll note that this has happened at least once before already.
