A root cause to this issue has been found; The BIOS Is leaving an
interrupt open to be serviced when handing off control to the OS. The
uhci_hcd module shares the same interrupt line and disables the handler
before the IDE interrupt is serviced.
In kernel 2.6.26 this issue doesn't occur in the exact same fashion, as
it passes through, but the number of interrupts is now very large.
