The only time I've had it ignore me was when one of the processes it was
trying to stop couldn't be stopped.

When you run through the scripts by hand, is there ever a time when the
stop script fails?

Can you take it down to runlevel 1 or does it ignore you there too?  Does
it ignore shutdown or just reboot?

What happens if you do an init 6 (instead of a reboot)?
