    Right. However if this is what Thomas was seeing the problem turned
    out to be an issue with pci_enable_device changing the irq number.
    It just happens that now the code cares, so the bug is found.

    Marcus any chance I could see an oops? Or you could try the patch I
    previously posted when debugging this with Thomas.

    I'm going to clean that patch up and send it along in hopes that it
    helps anyway and see where we land.
