Neil, Olli, My current guess is that one of the dracut script called during the shutdown process triggers the errors you're seeing. And it might be /usr/lib/dracut/modules.d/90dm/dm-shutdown.sh. Could you try to edit this file and add "set -x" right after the first comments. Then recreate the initrd with "mkinitrd" and follow the instructions from comment #14 ? Thanks.
