Here are the results of ksymoops < /var/log/messages. Sorry for the
lenght, the error is repeated many times. I don't know if that helps
to have them all. Would it help if I turn on Kernel profiling or any
other debug/profiling stuff ?

ksymoops < /var/log/messages
----------------------------

Options used: -V (default)
-o /lib/modules/2.2.0/ (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.

Warning in compare_ksyms_lsmod, module 3c59x is in lsmod but not in ksyms, probably no symbols exported
Warning in compare_ksyms_lsmod, module cs4232 is in lsmod but not in ksyms, probably no symbols exported
