Reboot does not work on any machine

[Albert Graham]

Hi Guys,

I'm hoping someone can throw some light on this problem.

Basically, reboot and shutdown do not fully work on any of my machines, 
(all are running Fedora 8)

The machines vary from Laptops to Desktops and Mini-PCs (e.g. Aopen 
MP965-DR) they are currently running
kernels version 2.6.26.3-14, but this problem started to appear last 
year sometime maybe around kernel 2.6.21 ish.

When I run reboot it outputs the following and simply sits there:

INIT: Switching to runlevel: 6
INIT: Sending processes the TERM signal
INIT: no more processes left in this runlevel

After pressing the power button, the system shuts down all the services 
with the last two lines stating instead of powering off.

Halting System...
System halted.

Then sits there...

However the real problem is the CPU seems to be running at 100% (this is 
a guess), but my laptop's motherboard (Cleveo D900T) burnt out :) - it 
was running MythTV front end and was turned off by the other half who 
didn't realize the machine was running... :(


Changes the power management settings in the BIOS makes no difference or 
whether or not acpid is running :(

Here is a list of services I'm running:

Any help would be very much appreciated.
