    Something in 2.6.24-rc* seems to be a lot more fussy about this kind
    of situation than in 2.6.23. I have a driver (sata_qstor) that manages
    a piece of hardware that unfortunately generates spurious interrupts

    With 2.6.23, it was only rarely bad enough to cause the "Disabling IRQ #nn"
    event to occur. But in 2.6.24-rc*, it happens almost immediately now
    (so, yes, I've gone and put a workaround into the driver for it).

    Something's different.
