Public bug reported:

After resuming from hibernate I have no network connection. This doesn't
happen with suspend, only hibernate. I'm guessing this is something with
network-manager as doing 'sudo service network-manager restart' fixes
the problem. ifconfig shows no eth0 interface but doing 'ifconfig eth0'
does return some info. It's like the interface is down or something

ifconfig
lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:65536  Metric:1
          RX packets:83613 errors:0 dropped:0 overruns:0 frame:0
          TX packets:83613 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:8178151 (8.1 MB)  TX bytes:8178151 (8.1 MB)

ifconfig eth0
eth0      Link encap:Ethernet  HWaddr XX:XX:XX:XX:XX:XX  
          BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:2442293 errors:0 dropped:0 overruns:0 frame:0
          TX packets:2655252 errors:0 dropped:0 overruns:0 carrier:0

1. Hibernate system (must manually enable hibernate in pm-utils)
2. Resume from hibernate.

Expected result:
Network connection is restored

Actual result:
No network connection. network-manager icon in system tray has a red X on it. Doing 'sudo service network-manager restart' brings the network back.
