Looks like page_launder is still causing problems.  I was using
ReiserFS version 3.6.23.  As far as I remember it was running
Seti@Home 3.03 and compile qt-2.2.3.  I was able to run ksymoops
without rebooting.

ksymoops 2.3.5 on i686 2.4.0-test12.  Options used
     -v /boot/vmlinux-2.4.0-test12 (specified)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.0-test12/ (default)
     -m /boot/System.map-2.4.0-test12 (specified)
