xfs_repair is ensuring that the problem is not being caused by on-disk
corruption. In this case, it does not appear to be caused by on-disk
corruption, so xfs_repair won't help.

Interesting. I think I just found a cause of this shutdown under
certain circumstances:

http://marc.info/?l=linux-xfs&m=120518791828200&w=2

To confirm it might be the same issue, can you dump the superblock of this
filesystem for me? i.e.:

# xfs_db -r -c 'sb 0' -c p /dev/sda2

Also, what the mount options you are using are?

Cheers,

Dave.
