I used the command "lspci -v" and found the devices using the same IRQ.
00:11.0 Ethernet controller: 3Com Corporation 3c905 100BaseTX [Boomerang]

I would guess that the number of interupts because of the Ethernet controller could cause a problem. I took the controller out. Fedore asked me to update the configuration but there was still IRQ sharing for the device. Both cards are in a different PCI slot, which is probably why their using a new IRQ#.
Thoughts?
