The early SIS chipsets with 2.6 kernels have all sorts of errors with routing irq's. You can use any combination or all of the following to try and isolate the problem.

pci=biosirq
pci=noacpi
noapic
nolapic
acpi=off

These are kernel parameters and need to be loaded on the kernel line in grub.

The symptoms I've seen are network cards that detect, load their modules but wont pass dhcp addresses or route static traffic.
Network cards that linux says aren't there, or wont load modules etc. I've changed cards etc and used those cards in other machines it's not until the above is investigated that I get somewhere.

Kernel parameters are documented in the kernel-parameters.txt file which is part of the kernel documentation packages.

It's good you figured out the problem, but please use the bug tracker next time so there is a  record for others as to what settings need to be used with different motherboards.  There is very little information on the web for hardware compatibility for RHEL4 - especially older hardware.

Hi all

This problem seems to be with 2.6 kernels in general. Ubuntu, Fedora now SME 7.
