I'm not sure if btrfs is to blame for this error. After the errors I switched 
to XFS on this system and got now this error:

ls -l .kde4/share/apps/akregator/data/
ls: cannot access .kde4/share/apps/akregator/data/feeds.opml: Structure needs 
cleaning
total 4
?????????? ? ?    ?        ?            ? feeds.opml

xfs_check is showing this:

xfs_check /dev/sda3
link count mismatch for inode 219998792 (name ?), nlink 0, counted 1
disconnected inode 220064328, nlink 1

So this is the second FS I've got suddenly errors, so I think the problem lies 
deeper. Adding some CCs for this.


regards,
  Johannes
