OK i hope you can reproduce it as well.

.config

I also found out that i was not able to reproduce it under a freshly new 
created xfs part. I needed to copy a bunch of files delete some create 
some new and then start the test. I just duplicated multiple times the 
root filesystem and then deleted some, created some hardlinks whatever...
