I don't think this > is correct. Is there some way how to work this around? You could try to insert the NIC into another slot and see if the problem persists. Some MoBos are designed in a way that some onboard HW shares its IRQ with a PCI slot. Additionally your BIOS might offer you a way to specify an interrupt for the slot in question. I don't know if FreeBSD honours this setting during boot, though. HTH Christian
