With both cards in with an array, only the first card to initialize will POST. The second card will say it was successfull, but the POST only takes about 5 seconds instead of 30+ like normal. The system does detect the array with lspci, but there is no driver loaded.
I have tried combinations of different PCI-E slots which only changed the boot order.
This is my only host at the moment so I can't shut it down till later.
I know these cards are compatible so it is the motherboard causing the problem. I didn't see much in the BIOS for an IRQ setting or something.
