Title:
No network after resuming from hibernate
Status in linux package in Ubuntu:
Incomplete
Bug description:
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

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.
