This is a completely different problem. The irq is properly setup >and received but none of the drivers wanted it. The irq with ioapic are shared with sata2 and audio, and later the audio driver get the irq, and then try to get MSI. The MAC first shared irq (ioapic) with SATA and it later transfer to use MSI without problem. YH
