This happens quite often, on two _different_ motherboards. (both SMP). Earlier USB had irq 5, now I have these lines: PCI: Via IRQ fixup for 0000:00:11.2, from 5 to 10 PCI: Via IRQ fixup for 0000:00:11.3, from 5 to 10 PCI: Via IRQ fixup for 0000:00:11.4, from 5 to 10 Have no idea if this matters. Hope someone could help me sort this out. Best regards, Stian
