What the IDE sequence is:

	disable_irq()
	probe_for_drive()    <- Generates an interrupt
	enable_irq()
	<< we get interrupted here >>
	request_irq()

It appears that the interrupt is queued and not dropped on the floor.
It is my understanding that it is hardware dependent if it gets queued
or dropped when ibm,int-off rtas call is made.

Thanks,
Jake
