PIII 650 UP. kernel tainted by speedtch.o (usb Speedtouch Alcatel driver).
OOPS logged in /var/log/messages during shutdown (the 2 oops come together).
*It is not repeatable*. I haven't catched such oops with 2.5.8-pre3.

I hope it can help.


   ksymoops 2.4.5 on i686 2.5.8.  Options used
        -V (default)
        -k /proc/ksyms (default)
        -l /proc/modules (default)
        -o /lib/modules/2.5.8/ (default)
        -m /usr/src/linux/System.map (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.
