A little while ago, I reported a crash with 2.4.20ctx16. Now, it has
happened again, and I have captured much more debug info:

ksymoops 2.4.8 on i686 2.4.20ctx-16. Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.20ctx-16/ (default)
     -m /boot/System.map-2.4.20ctx-16 (default)
