Just a quick reply to myself: The problem seems to be that the the IRQs
of the motherboards on board network interface and the AGP card are the
same. This works for a while but then something goes horribly wrong and
all comes to a halt. Why the IRQ is shared I have no idea as there are
nine free IRQs.
Unfortunately there is no way to change either of the IRQs in the BIOS,
so I've had to resort to replacing the on board gigagit network
interface with an add on 100Mb interface. All seems to be working
properly now with the NVIDIA driver.
