I also have seen this, but I wonder if it's not because we're using the
interruptless driver, and the hardware is still sending interrupts.  Since
the kernel doesn't know who is supposed to get the interrupt (driverwise)
it would seem that you would get this message.  (Not that I've looked at the
source or anything.  :)  )

Sean Berry is a computer scientist trapped in an engineer's mind.
I imagine someone is likely to misinterpret my opinions as those of my
various employers.  This is not the case.
