Hi,
I seem to have crashes with the 334.* drivers on linux. Driver 319.76 is rock solid. tested with both 334.16 and 334.21 and I get the crashes below:

Some info:
kernel: Linux desktop 3.13.7-custom #1 SMP PREEMPT Wed Mar 26 23:21:07 EST 2014 x86_64 x86_64 x86_64 GNU/Linux
CPU: Intel(R) Core(TM) i7-4930K CPU @ 3.40GHz
I have enabled MSI interrupts via the use of an conf file for modprobe.d:
options nvidia NVreg_EnableMSI=1
This was done as I did not fancy the device sharing interrupts with a USB controller!
Looks like I will have to go back to the 319.76 driver… :(
