I'm having the same problem with my MVME2700 with an ncr53c8xx chip.
I did a little debugging and checking.  In my previous kernel version
that I had running (2.2p4), it chose to use interrupt 14 for the chip.
In 2.2.9, it chose to use interrupt 19.  But that is the only thing I
can find.

If anyone has a solution I'd like to know.
