[Bug 1010045] Re: 12.04 hangs on shutdown deconfiguring network interfaces

[David Martin]

:-)) Seems to be fixed. It was an "old friend" of mine...

I removed much software installed during the last week. But only after
this one I got the shutdown in time. Boot process seems to be faster now
and a lot of OpenSSH start/stop messages are gone:

  sudo apt-get purge avahi-daemon libnss-mdns

It's about Zeroconf and APIPA IP numbering, but I don't think it is
necessary for desktop servers.

So, I'll try to reinstall things and get my system back to production.
On the other hand, I still don't understand why this didn't bother us a
couple of weeks ago...

Regards
David

  We only have this issue when a vm has multiple network cards assigned.
  When we do a manual "/etc/init.d/network stop; halt", the vm shuts down like expected.

  dpkg -l | grep ifupdown
