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

ifconfig eth0
eth0 Link encap:Ethernet HWaddr XX:XX:XX:XX:XX:XX

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.
