I have 2 identical 3Com network cards in a Compaq 6400R server. 
I just installed RedHat 7.1 (a clean install) and I'm getting an
IRQ conflict on one of the network cards:

Interrupt posted but not delivered -- IRQ blocked by another device?

Eth0 works fine and I can connect to the server through it. Eth1 is not
accessible.

I'm not a Linux master. I can't find anything obviously wrong with the
configuration. I've included the following debug info. (Sorry it is so
long):

dmesg
/proc/pci
ifconfig 

Any help would be appreciated.

Dan
