This is just a shot in the dark, but do you have the manual for your 
motherboard?  On mine there are a couple of pci slots that share irq.  
Maybe changing the slot with one of your cards would help.  There is 
probably an easy way to check irq values by cli, but I don't know what 
it is.  You could check in bios and assign values to each card as your 
motherboard manual suggests (mine suggested certain values for each type 
of card, so I am assuming yours would too).  Someone else will probably 
have a better answer for you.  Good Luck!
