Could you try to enable xfs debugging before doing these stats? You
can use the setdebug command (do a "make setdebug" in xfs/linux in
your object directory). "setdebug on" will enable full debugging, and
"setdebug off" will turn off debugging.

Does the machine lock solid, or is it only the ls -al that locks? Can
you abort it with ^C?
