I have 2 times quad GTX 780 running on X79 boards for CUDA on Ubuntu 12.04. I experience on the GTX 780 a dropout of the driver after about 30 hours of runtime. System reports that I don’t have Nvidia drivers running an longer. I have read something about a 36 hour TDR bug that has been fixed on Windows. Is that related? What driver do you recommend for Linux? I have no problems with my 6 Titans running in 319.32. All 319 drivers don’t see 4 780 cards, 325.08 worked for some time (< 30 hours), 325.15 crashed once - trying to reproduce.
I don’t have a nvidia-bug-report.log for this yet, I re-installed drivers after the crash.
EDIT: I have now attached the bug report and logfile.
