Thanks to Ben and David Blythe for your responses.  Indeed I think you
are correct.  Unfortunatly I found a patch posted by Gunther Mayer on
the Linux-kernel mailing list which does not seem to fix things either.
His patch looks like it does what David described; disabling interrupts
and then reenabling them in init_irq...  But it does not work...  ;-(

At this point the only thing I can think of is that the device is not
responding to the interrupt disable?  Or I have missed something with
the patch.  David, you would not happen to be able to send me a patch or
your entire ide tree?

Oh well I just thought I would thank you guys for leading me the correct
way.

Thanks again,
