I've been seeing a number of strange messages in my log since
updating to 6.0-RC1. Usually they happen when some intense
disk access is happening (e.g. when /etc/periodic/security/100.chksetuid
is running at 03:01), but it doesn't happen _every_ morning, and
it doesn't always happen if I manually run the script.
It also occasionally happens at times where I wouldn't say I was doing
much with the disk.
I'm hoping nothing bad is happening to my data. At least, fsck
doesn't mention any problems, and I haven't noticed any corruption yet...
I'm on an AMD64 system, with an MSI K8T-Neo2 motherboard.
