My first guess would be some sort of PCI address assignment issue.
How many PCI slots does the board have, and which of those are sharing
irqs/etc with your motherboard components?

I know you have the "grunt" to handle that many cards, but I've never
seen a machine take 6 high-bandwidth PCI devices, no matter how
expensive the system was.

Your first troubleshooting could be to keep the adapters from
initializing and then insmod them one by one to see which ones cause
