Well, we're getting closer! Our driver currently doesn't put in useful messages, but I think I could sprikle a few in that might make that solution work. Or at least add a few so that checking through /var/log/messages* might do the trick. Unless I can figure out how to get something specifically into dmesg from our driver so as to avoid sifting through multiple matches. The other route I'm pursuing is using the functions from /usr/include/pci/pci.h to get pci device information. If I can get the devices and check their vendor and device ids then I could match IRQs as well. Unfortunately I don't have any man pages for those functions. Drat. Guess it's off to google if I decide to pursue that further. Thanks! Clay Fandre wrote: > > Ahhh, you're right.
