    The BIOS default setting is to have all PCI interrupts on 11.
    Try spreading them out manually.

    Ohhh. I recognize that one, I had problems with that one too. I solved
    it by adding hci_usb to the hotplug blacklist. However, after
    upgrading to 2.6.8-rc1-bk2 (from 2.6.6, so the fix might have been
    somewhere in between), I could safely remove that from the blacklist
    again. YMMV.
