But that was a long time ago ;) tune2fs -l /dev/loop0 Any special mount options in /etc/fstab ?

It doesn't, my machine is running all fine. Thanks, that narrows problem to yet unidentified kernel change that causes loop-AES code to misbehave. > * it seems to appear faster when the system is under load, e.g I'm compiling > stuff while working.

I installed kmail on my test box, but as of this writing ~/Mail dir has only few zero length files. Someone, possibly you, posting a script or clear "do this, that, and that" instructions would be of great help.
