That actually makes sense - it seems to be IRQ 7 that is causing an
interrupt storm.  I am thinking perhaps it has something to do with
the message about forcing the bios to give up possession of the
device.  I did try checking for and ack'ing interrupts on the ehci
device when forcing it out of the BIOS's clutches but that didn't seem
to help any.  The other thing I was going to try was tweaking the bios
to reserve IRQ 7 just to see of the problem persisted.
