    I'd very much like this one to be two pass, with the second pass occuring
    after interrupts are disabled. There are some horrible cases to try and
    handle otherwise (like devices that like to jam the irq line high).

    Ditto on return from suspend where some devices also like to float the irq
    high as you take them over (eg USB on my Palmax). From comments Ben made
    ages back I believe ppc has similar issues if not worse
