    Hi Ralf,

    Thanks very much for your report. It looks like this device is the problem:

            0000:00:06.0 Multimedia audio controller: nVidia Corporation nForce2 AC97 Audio Controler (MCP) (rev a1)

    and it should get IRQ 21:

            ACPI: PCI Interrupt Link [APCJ] enabled at IRQ 21
            ACPI: PCI interrupt 0000:00:06.0[A] -> GSI 21 (level, high) -> IRQ 21

    The driver for this should be intel8x0.o, and it looks like you are
    loading it as a module. Could you build it in statically to the kernel
    and collect the complete dmesg from a boot with "pci=routeirq" (one
    from the boot that hangs would be nice as well, but that is a pain to
    collect unless you're using a serial console)?

    The usual problem is that a driver looks at pci_dev->irq before calling
    pci_enable_device(), but intel8x0.c seems to be doing the right thing
    in this regard.

    Bjorn
