Every now and then, however I cannot capture the oops right now. It
looks completely different. One I got after this session 5 minutes ago:

node:~# mount
/dev/sda1 on / type ext3 (rw)
/dev/sda3 on /var type ext3 (rw)
/dev/sda4 on /usr type ext3 (rw)
nodev on /dev/oprofile type oprofilefs (rw)
sysfs on /sys type sysfs (rw)
loghost:~# lsmod

Thanks for your feedback. I will get to lkml as soon as I have something
people can actually reproduce, not involving rmmod -f, and which I can
capture. No need to further look into it.
