Comment 41 for bug 616287

keith, sorry that you feel this way.

We're actually getting close to a fix for another bug, which I think is probably the same thing... (not sure its a strong enough feeling to mark it duplicate yet)..

see bug #688541 for some suggestions which we're considering to fix this.

In fact, it would be interesting to hear from people who are affected what the result of this command shows:

fgrep "stop on runlevel" /etc/init/*.conf

Yields. It should show quite a few things from the base install, but there might be a common service or type of service which is too slow to shutdown.
