Hi Togami,
It will be nice if you can provide some information regarding the filesystem set up you have in your system. Like which filesystem you were using.
Are you able to recreate this problem?.
Thanks

Hi Togami,

Plain ext3 with UTF-8 filenames, no ACLs or Extended Attributes. It was created with last week's RH rawhide then I moved to 2.5.70, uptime 5 days now.
Should I be worrying about filesystem corruption now?

Unfortunately no. I just noticed that message in dmesg after 5 days of uptime. Hmm, I just noticed this line within that last post:
<6>note: updatedb[18515] exited with preempt_count 1
If it happened during updatedb, then it must have been around 22 hours ago during cron.daily's updatedb. My laptop was completely idle during that time.
