In my case it appears that it was the symptom of severe bus problems.
About 5 minutes after I posted the initial report I discovered that
the cable from the back of the Nikon to the MO drive had fallen off so
the bus was running unterminated. Replugging it fixed teh bus error
and the oops.
Looks like error handling is all fscked up...

I saw this oops too. The following patch is working for me, but I don't
know this is a correct fix.

Just upgraded from 2.4.3 to 2.4.5-ac13 and get an aiee, killing interrupt
handler on boot as aic7xxx.o is loaded. I have an Adaptec 2906 PCI card
with a Nikon CoolscanIII and an HP optical drive attached. Works ok on
aic7xxx_old. Works with an initial bus reset on 2.4.3. Dies a horrible death
on 2.4.5-ac13.

On 2.4.3 I get the following errors when aic7xxx loads

It then carries on and works.
Ksymoops output follows but may not be entirely reliable
because it's from a hand written file and /proc/ksyms and /proc/modules are
from 2.4.3.
