Re: 6.1-Stable Freeze with 6600GT
Just to reply to myself again: It looks like that sharing the IRQ with the network interface was the problem. I installed a separate network card and disabled the onboard device in the BIOS and all seems to well now. So far my system has not frozen all morning.
So the moral is: don't try to use an MSI K8T Neo2-F V2.0 motherboard with the NVIDIA driver as they don't like sharing the same IRQ as the network interface.
