Not an XFS problem.  You still have a process running that is holding /
open.  Edit /etc/rc.d/init.d/halt, after

  # Try them all, one last time.
  umount -a -f

add

  ps xa
  lsof /

That will tell you which process is holding / open.

A normal side effect of being unable to umount /.  Fix the umount
problem and this will go away.

Normal kernel debugging messages from drivers/block/ll_rw_blk.c,
nothing to do with XFS.
