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

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.
