Our terminal server using cyclades-z is experiencing oopses....

Here is an output of ksymoops fed with an oops I encountered, seems like
the cyclades module is involved so i'v cc'ed cyclades too.

As an additonal Info i'm using 2.2.5-ac4 compiled using egcs-1.1.2
with mostly everything compiled as modules.

Options used: -V (default)
-o /lib/modules/2.2.5-ac4/ (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-m /usr/src/linux/System.map (default)
-c 1 (default)
-a - same as ksymoops (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
