Re: System hangs with nvidia-driver
I suspect I've seen this problem as well with the more recent FC4 kernels, and after discussion with development it was determined to be a kernel bug, not a driver bug. For what its worth, the problem does not seem to occur with the latest FC5 test kernels.
If you could capture the crash output in a serial console I could confirm whether you're seeing the same problem. Without that output, I'm afraid there isn't much more that I can do.
