Rogan,
Was the kernel upgraded? If so, can you downgrade it to the
previous version? To be honest, this looks like a kernel problem
to me. NetworkManager successfully started, then it looks like
something immediately told it to shut down again -- probably
whatever it was that told the rest of the system to shut down.
Unfortunately, the syslog doesn't say what that was. :-( (And
I've always found NM's syslog messages to be quite inscrutable.)
I would try downgrading the kernel, if you can, and see if that
fixes it. If so, you get to file a bug report. :-) You might
try asking on the Ubuntu IRC channel (#ubuntu on irc.freenode.net,
I think), or the Ubuntu support forums.
I'm sorry I can't help more, but that's all I can think of.
