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?
It seems to work fine with skge disabled.
If it's an
on board device, you can probably disable it in the BIOS configuration menu.
Thanks.
