 Ok, obviously this panic has nothing todo with the chown or chroot, I got a 
 very similar one while the machine was doing pretty nothing (MUA, Browser 
 and a hand full xterms, all more or less idling).
 
 Here's the message and the trace:

 System is like originally mentioned 6.0-beta4, seems to be a show stopper 
 for 6.0-release...
 
 Thanks,
