Bug description:
  Binary package hint: network-manager

  After resuming my laptop from Suspend-to-disk, NetworkManager failed to give 
me an IP. Usually it gets an IP from DHCP server without problems; but this one 
time it failed. First dhclient correctly got an IP:
  Apr 10 19:32:43 veridian dhclient: bound to 192.168.0.4 -- renewal in 17299 
seconds.

  A short time later it releases the IP again:
  Apr 10 19:34:14 veridian NetworkManager: <information>^IDevice 'eth0' DHCP 
transaction took too long (>99s), stopping it. 
  Apr 10 19:34:14 veridian dhclient: There is already a pid file 
/var/run/dhclient.eth0.pid with pid 1320
  Apr 10 19:34:14 veridian dhclient: killed old client process, removed PID file
  Apr 10 19:34:14 veridian dhclient: DHCPRELEASE on eth0 to 192.168.0.1 port 67

  
  ifconfig showed this:

  After left-clicking on NM icon and selecting Cable Network, it got a
  correct IP.
