the reason i ask because the following happens:
on a system with one pci network card and my pci device, my device driver's
interrupt handler gets called without anyproblems when i issue an interrupt.
but on a system with two pci network cards, it seems like my interrupt
handler never gets called when i issue my interrupt... any idea as to why
this happens?
