[Bf-cycles] nvidia module crashes on linux 64bit with 2.66a

[Dimosthenis Kaponis]

Hello all,

I just upgraded blender (64bit) to 2.66a and I am experiencing nvidia 
kernel module crashes (that lead to a system crash) when I am using GPU 
Compute in Cycles.

There have been no other changes to the machine, hardware or software 
and the card does not misbehave in linux or Windows 7. It also did not 
misbehave at all in my previous 2.65 install.

I am suspecting something in Cycles has changed and might be triggering 
a bug in the nvidia module that leads to a crash. Note that whenever the 
crash occurs it happens not while Cycles is rendering but a few seconds 
after it finishes.

The card is an Asus Nvidia GeForce 2GB GTX 680 DirectCU II OC. I have 
tried several versions of the nvidia proprietary driver up to 310.32.

Any advice is welcome (and if it proves that Cycles is, indeed, causing 
this, I hope my mention helps expedite the fix).


Best,

Dimosthenis.
