No ip from dhcp (com.redhat.dhcp.OperationInProgress)

[Paulus Esterhazy <pesterhazy gmx net>]

Hello developers,

I'm using network-manager 0.6.4-6ubuntu7 from soon-to-be-released Ubuntu 
feisty. This looks like a bug in networkmanager - perhaps you can shed 
some light on the reason why this happens.

When I resume from hibernation with only a wired via-rhine based 
ethernet card plugged in, I get no IP address from dhcp. When I 
"deactivate network" and manually do "sudo dhclient eth0", it works 
immediately. Deactivating/reactivating has no effect, neither has 
killing and restarting all nm processes.

A report on launchpad:
https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/102716

There's also a similar bug in openSuSE:
https://bugzilla.novell.com/show_bug.cgi?id=254412

Here's a syslog excerpt. As you can see, running dhclient manually works 
fine.
