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.
