Fedora 14: Shutdown problem

[Terry Barnaby]

Hi,

About 1 in 4 times Fedora 14 hangs during shutdown on at least 4 of my systems.
Looking at the shutdown messages (ESC in the splash screen) and adding some 
debug statements to /etc/rc.d/rc0.d/S01halt, it hangs after the messages:

	"Unmounting file systems"
	"init: Re-executing /sbin/init"

with the message:

	"mount: you must specify the file system type."

Adding some debug, this appears after the following command is executed:
	"fstab-decode mount -n -o ro,remount /dev/sda1 /"

The file system is ext4 on all of the systems and that command looks ok.

Any ideas ?

Terry
