[Virtual-pkg-base-maintainers] Bug#818864: base: eth0 removed during suspend

[Mike Booth]

Package: base
Severity: normal

Dear Maintainer,

        If I suspend the system, I lose network connectivity when I resume.
eth0 is simply gone. A reboot restores network connectivity. The first thing I
tried was changing eth0 from DHCP to static. No effect.

        After some research I used the following command to debug network-
manager during suspend/resume:

service network-manager stop && NetworkManager --no-daemon --debug --log-
level=debug

Snippet:

sleep requested (sleeping: no  enabled: yes)
NetworkManager[1672]: <info> sleeping...
NetworkManager[1672]: <info> NetworkManager state is now ASLEEP
NetworkManager[1672]: <info> (eth0): device state change: activated ->
unmanaged (reason 'removed') [100 10 36]
NetworkManager[1672]: <info> (eth0): deactivating device (reason 'removed')
[36]
NetworkManager[1672]: <info> devices removed (path:
/sys/devices/pci0000:00/0000:00:1c.7/0000:04:00.0/net/eth0, iface: eth0)
NetworkManager[1672]: <info> wake requested (sleeping: yes  enabled: yes)
NetworkManager[1672]: <info> waking up...
NetworkManager[1672]: <info> NetworkManager state is now DISCONNECTED

Thanks!
