Fedora 12 + SDK 3.1 + driver 256.35 = malfunction Fedora 12 + SDK 3.1 + driver 256.35 = malfunction

I have a problem with new SDK 3.1 and the new driver 256.35.

My code compiles and runs perfectly on Fedora 10.

However, when I compile and run the code on Fedora 12, the following happens:

  1. The first time after the boot, the code runs, with no errors or signs of trouble.

  2. The second time, the code fails to find GPU with the followng error:
    NVIDIA: could not open the device file /dev/nvidia0 (Input/output error)

After the error, the only way to bring to the working state is to reboot.

Anyone knows why this happens and how to overcome this problem ?

I have seen something similar happen on my laptop as well.
Got frustrated, moved to archlinux.

256.35 and 256.44 both work nicely on OpenSuSE 11.3. gcc is 4.5.0. Tested both on a laptop with one GT 330M (Samsung R580) and a desktop with two GTX 460.

How well does CUDA 3.1 (SDK etc) work with OpenSuSE 11.3? Any issues due to official support only for 11.2?

Thanks!

Do you have kmod-nvidia installed on your machine ? If so, try disabling it and reinstall the 256.35 driver again.
