No, I didn't mean xfs_db. That examines the data structures on disk,
but apparently they're clean anyway.

What I meant is to rebuild the XFS with the CONFIG_XFS_DEBUG set.
With that option XFS has much more checks in place and hopefully
will assert earlier, giving us more clues.
It would be great help to XFS developers, but I'm not sure if it's
too much to ask for.
