| |
Hi,
I just picked this up from /dev/vcsa10 (and /var/log/{kernel,messages})... seems to have happened upon `rmmod reiser4`. Did not luckily seem to make the system unusable.
Kernel-version: SUSE Kernel of the day 20041029 Reiser4 fs were not mounted at the time of the rmmod (that's logic), but were mounted before.
The backtrace does not give much info (and ksymoops neither), so the best I could suggest is checking whether these codepaths allow unfreed objects. Since the KOTD I'm using is also a month old by now, don't invest too much time into this, if at all.
