XFS does NOT journal data by default. I've tried and used it and found myself 
with empty files after a recover. I wouldn't be surprised at all if this 
superblock overwriting were indeed an XFS bug.

I wouldn't trust XFS today, even though its stability has vastly improved in 
the last year. If you want to be safe, use ext3. It may not be the best 
filesystem per design, but it sure is the most stable when you use Linux.
