Usually, this might be the case, as lockdep reports only once and when 
it does it's usually the morning after the last reboot, when a script 
runs the backups (so the box is under load, probably memory pressure 
involved). However, this time I don't remember memory consuming tasks 
running. Unfortunately, I cannot reproduce this yet...

thanks for your explanations,
Christian.
