I'm afraid I don't have another system at the moment to upgrade to FC4 I will
work on getting a new drive to do a temporary install of FC4 maybe FC5 to see if
this bug still exists.

I can say however that the latest FC3 kernel 2.6.12-1.1381_FC3smp still exibits
this bug.
I'd also like to reiterate that it doesn't matter what kind of USB device is
plugged in, any USB device attached to the system when the computer shuts down
will prevent power down

I did some test on this kernel to determine exactly what happens in the final
stages of shutdown

Disks sync
Disks powerdown
Keyboard and Mouse (on PS2 jacks) powerdown
acpi_power_off is shown

system does not power off
The graphics and CPU etc continue to run.

Non SMP kernel does the same thing

If there are no USB devices attached to the system then it will power off 
correctly

There are a few other ACPI poweroff bugs floating around at the moment.
It might be an idea to get those people to try removing all USB devices an see
if their systems will power down.  If the keyboard is USB issue a poweroff
command and then unplug the keyboard, this still works.

I'll see what I can do about getting the latest FC5 tests and giving them a go
on this machine.  But I'm extremely busy this week / weekend and this computer
can't be down for to long

Thanks
    Richard
