Yep. When I had SU+J enabled I could never get fsck to ever mark the 
disk as clean. It was permanently dirty with errors that it claimed it 
fixed but then you ran it again and the same errors came back. Only way 
to fix it was to switch off journalling and just leave softupdates only 
enabled. Then fsck marked the disk as clean as you would expect. I still 
to this day don't understand why SU+J is the default when it's clearly 
so broken.
