After this /usr was dirty and I had to run fsck against it.
There was immense amount of inode reconnect request that I had to perform and pressing [y] + enter took me 5 minutes! :P

I also remember that it wanted to create lost+found(I said yes) and Soft Updates have been mentioned...

What is a cause of this?
 
When I used UFS, sometimes after power failure (when I was a complete noob and didn't knew about -y) I was doing same practice.... there were few times I cursed on FreeBSD because it was very long process...
 
This is crazy!
Now I have page faults...

Maybe, there is an issue with CPU, or it's L1, or L2, or Lx cache??
Which tool should I use? :stud
