I have had occasional issues with PCI NIC's inexplicably refusing to send traffic if they shared an IRQ - this was not an OpenBSD issue, since in those cases the problem was not corrected by using a different OS. NIC functioned fine when IRQ was no longer shared. Now, I had always assumed it was because of a problem with the NIC itself. Apparently, I am about to find out I was wrong :-).
