[Bug 1187530] [NEW] Cannot re-establish network connection after resuming (from suspend to RAM)

[Francis Lamonde]

Public bug reported:

Kubuntu 13.04 64-bits

When suspending to RAM and resuming, the network connectivity is not re-
established on resume. I am expecting connectivity to be re-established
and IP address assigned, but no IP is assigned.

I am using a script to suspend to RAM, here is the command line
launched:

dbus-send --print-reply --dest='org.freedesktop.PowerManagement'
/org/freedesktop/PowerManagement org.freedesktop.PowerManagement.Suspend


To re-establish connectivity I tried 'service network-manager restart' but that doesn't re-establish it.
Loging out KDE session and back in does not help either.


When I resume, I get this:

-----
~$ ifconfig
eth0      Link encap:Ethernet  HWaddr 00:21:91:21:d5:0d  
          inet6 addr: fe80::221:91ff:fe21:d50d/64 Scope:Link

But in eth0 it should show like this:

-----
eth0      Link encap:Ethernet  HWaddr 00:21:91:21:d5:0d  
          inet addr:1.2.3.4  Bcast:1.225.255.255  Mask:255.255.0.0 (the IP address has been changed for posting)
          inet6 addr: fe80::221:91ff:fe21:d50d/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:235 errors:0 dropped:0 overruns:0 frame:0
          TX packets:279 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:36696 (36.6 KB)  TX bytes:27691 (27.6 KB)
          Interrupt:18 Base address:0x6c00 
-----

It's missing the INET address line, for the most of it.


Not sure if that's normal, but I also get this:

-----
~$ sudo ifup eth0                                                                                                                                                    
Ignoring unknown interface eth0=eth0.

I checked pm-suspend.log, here it is:

As you can see I even tried to have a script run the network-manager
restart, which it did successfully but still no IP assigned to eth0.


Thank you
