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. Nigel.
