No. Linux guarantees that YOUR interrupt will not occur. This means
that you have free reign about your own device (the ncr8xx). However
if you cannot tolerate being interrupted for a few microseconds, (e.g.
if the device has a microsecond timeout after writing a "low word")
you can opt for running the whole interrupt routine with interrupts
off to keep things "consistent".
I don't think that the NCR is that badly designed, and that running
with interrupts enabled (all other interrupts) is acceptable.
