APIC is used to route interrupts differently. You can also disable it from the loader with 'hint.apic.0.disabled=1'. I've looked at your dmesg's, and the problem is that in the ACPI case the IRQ 10 that your USB controllers are using is configured as an ISA IRQ (edge/high). For now you can either disable APIC or ACPI as a workaround until I figure out a better solution. -- John Baldwin <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.org
