Today I got some kernel oops again.
The output of ksymoops is attached. I am absolutely not familiar with tracing
kernel bugs, so I hope the information below is useful for you. If not,
please email me what to do.

My system is Debian Woody with the woodie's 2.4.18-k6 kernel as appearing in
the log running on an AMD K6-II and 192MB RAM and 2 IDE harddisks.

Best wishes

Dirk

ksymoops 2.4.5 on i586 2.4.18-k6. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.18-k6/ (default)
-m /boot/System.map-2.4.18-k6 (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.
