As Greg said, it will let you figure out which cards the BIOS is trying to have share interrupts.

I'm tempted to say the NIC is fighting with something - "mrxsmb.sys" looks like MS networking. (And it will be using the one in system32.) Google confirms this including that rdbss is part of the same functionality. Try putting the network card in a different slot. Sometimes they don't like sharing, especially with sound cards.
