This problem seems to be related to later kernels, and some hardware. for 
example, FC5 on an Aiiifriend machine, celeron 1.3Ghz. The kernel that was 
installed originally from the cdrom install shuts down the machine ok, but 
later kernels had a problem. After some posts to the list Tim suggested 
acpi=force , and this worked for me with FC5. Aaron Konstam had similar 
problems with FC6, and for him lacpi worked. And that is lacpi, not lapic 
appended to the kernel line in Grub.

There is clearly some problem in the way that kernels 2.6.17, and later are 
handling shutdown on some hardware.

On my other machine, an old Gateway 500, using a P111 katmai, FC5 has no 
problems shutting down completely no matter which kernel I bootup with. I 
also have FC6 on this machine, and that shuts down completely as well.

Just my 2¢ worth.
