For starters, what is the blocksize on your filesystem?  xfs_info /mount/point 
will tell you.

I would guess that this is stale disk date coming through, but not certain. 
I've seen something like this but only when block size < page size.

But the default block size is 4k, and it also looks like you are running on a 
4k page system, correct?
