Not a fix as such, but perhaps a hint for a work-around:

I managed to make my GA-K8NF-9 board happily use a plug-in Intel
21143 PCI network card by forcing the PCI slot->interrupt
mapping in the BIOS, rather than leaving it at the default
"auto".  Before this it had always just "timed out", and
basically didn't work, even though it probed OK.

Unfortunately the BIOS on this board doesn't let me do the same
thing for the on-board peripherals, or else I suspect that the
NVidea MCP9 GBE interface on the board might work a bit better.

Something to try, anyway.
