So init knows that you want to shut down/reboot..

My guess is that one of the "early" init scripts are hanging.

To verify that this is the case, you could try to execute each of the
scripts in /etc/rc6.d/* scripts in asciibetical sequence. I suspect
something like this would do the trick:

   for file in /etc/rc6.d/K*; do echo == Running $file ...; $file stop; done

If my suspicion is correct, then one of the scripts will hang...

Hope this helps
