Happens to me too after I upgraded to Kubuntu Lucid. Whenever I have a problem with standby, shutdown, or resume (about 1 in 4 times, alas), after I power-off and reboot I have no network and KDE's knetworkmanager shows "Network Manager disabled". Every time I looked /var/lib/NetworkManager/NetworkManager.state contained NetworkingEnabled=false. Regarding comment #24, my /etc/network/interfaces is unchanged since 2009-10-14 (Karmic?) and contains
[main]
plugins=ifupdown,keyfile
[ifupdown]
managed=false
and regarding comment #2 my /etc/network/interfaces dates from 2009-04-25 (Jaunty?) and contains
auto lo
iface lo inet loopback
