Subject2.2.5 with aic7xxx update still oopsing
I've updated my 2.2.5 with Doug's latest aic7xxx driver. But I
still get those strange oopses that I could trace down to 2.1.130
(I haven't tried earlier kernels). I still got no _real_
explanation for this oopses. Attached is the ksymoops output.

Regards
Martin

The solution of this problem is trivial and is left as an exercise for
the reader.
Options used: -V (default)
-o /lib/modules/2.2.5/ (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-m /usr/src/linux/System.map (default)
-c 1 (default)

You did not tell me where to find symbol information. I will assume
that the log matches the kernel and modules that are running right now
and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc. ksymoops -h explains the options.
