    Bjorn, Linux kernel devs,

    when booting with a recent kernel (2.6.9-rc2-mm2), usb_ohci fails to
    initialize the USB bus and no USB device will work at that point.
    Adding pci=routeirq fixed the problem.

    I believe this has been working with earlier kernels, but I don't use
    USB often enough to remember.

    The PC is an Compaq (HP) Presario 2100Z notebook.

    Here's a diff of the dmesg output of two boots with and without pci=routeirq:
