Though I suppose I can use apm to do this as well. On a uni-processor system, isn't the ACPI tables used to setup the IO-APIC bits to have PCI IRQ routing so that I have more than 16 interrupts? This was another reason I had enabled ACPI. When I do get those interrupt problems, my network still continues to function while the USB mouse fails. I do agree it's not USB specific. It's more tied in to ACPI/(IO-)APIC. When I get back home, I'll try booting it with acpi=off on pre4 and see how it goes.
