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)

So, can you (or anyone) reproduce any oops/indication of a kernel
problem without having 'other' stuff in the kernel? If so, describe
please.. tis not of necessity an indicitation of problems with your
favorite application or driver if it is required to reproduce problem,
but _is_ much easier to diagnose the root if you can provide a formula
for failure [even obscure] which does not include 'foreign' material.
I've not seen a reproducable report yet.. but the reports which I've
seen ~jibe wrt 'there is something fairly odd going on'. (yes, I've
my share of oddities, and no, I don't have anything solid either;)
