OK, it did. Thanks.
With your patch none of the trace gets printed, so maybe the stack is really messed somehow. Now I get the oops, but the machine wakes up and works normally afterwards. The output is:
ksymoops 2.4.9 on i586 2.4.23-pre7-ford. Options used -V (default) -k /proc/ksyms (default) -l /proc/modules (default) -o /lib/modules/2.4.23-pre7-ford/ (default) -m /boot/System.map-2.4.23-pre7-ford (default)
Warning: 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.

OK, I added the addresses back.
