This problem only seems to happen with some hardware, and with more recent kernels. I have the problem on one machine with FC5, and kernels later than 2.6.17, although the original 2.6.15 kernel shutsdown the machine completely. On the same machine Fedora 7 has the same problem. On the other machine (different hardware) FC5 shutsdown completely with all kernels. There are a couple of options you can try for a start. When you boot up and get the Grub menu, choose the kernel you want to boot from, and press "e". Add one of the following options to the kernel line. Do one space before the option. When you have added the option press "b", and the kernel will be booted with the option. When booted, now see if it will shutdown completely. If not, remove the first option, and try the other. acpi=force lacpi Acpi=force worked for me, and I know that lacpi worked for someone else. There are other options, but you may have to look back through the list archives, as this problem has been discussed quite a lot. If one of the options works, you can add it permanently to the kernel line by editing /boot/grub/grub.conf. All the best. Nigel.
