I am using a PCI analyzer and it shows the bus in an idle state after

couple of interrupts from the card which appear to be handled

I'd try to check with other machine using "secondary" bus slot.
BTW: Are you able to analyze the "primary" bus transactions while
using the card in "secondary" bus? Perhaps there is something
wrong in front of the motherboard bridge?
A broken motherboard may be hard to diagnose, unfortunately.
Can you post something like "lspci -vv" taken on both machines?
I will post more info on Monday when I am able to power them up.
I'm not so sure the motherboard is broken, I am leaning more towards a
misconfigured
bridge. This computer is a 4U 19 inch rackmount chassis with a PCMIG
CPU and a 12 slot PCI backplane. I have done a lot of testing with this
box trying to characterize this problem. In one case I have put 3 Intel
PRO 100S NICs on the secondary PCI bus and they ran under heavy stress
test loads overnight. The 4 port NIC seems to be the only card that
doesnt want to cooperate.
