On my box the interrupt is solely used by ata_piix. Ah right. ata_piix could be screaming when the skge requested IRQ#5, but ata_piix is in native mode meaning that the PCI device is probably in disabled state when skge requests IRQ#5. Michal, can you please test the machine with skge disabled? If it's an on board device, you can probably disable it in the BIOS configuration menu.
