lspci -vvv is also usefull.

But the point is to go look at the pci interrupt assignments *before*
the hang occurs. I've seen the same situation, where two devices are
sharing an interupt, one on the mobo, the other in a PCI slot... it's
never been a good thing in my experience. As Eric pointed out if they're
both on the mobo you have to hope the designers built the hardware to
handle that, or if they're both in pci slots you can usually expect
the cards will play well with others. It's the third case that's
trouble, and then it's time to do as Eric did - get into the bios and
change the assignements (or in this case something that would cuase a
change to happen).
