Comment 11 for bug 45696

In my laptop system with one wifi card (ipw2200) and one ethernet card (both built in), I think the problem is caused by changing interface names: After system boot, the network devices are named eth2 and eth3, eth0 and eth1 don't exist. Network Manager works.
After a suspend, the devices are called eth0 and eth1, so Network Manager doesn't find them anymore. I can still configure the renamed devices using ifconfig and iwconfig.
Restarting Network Manager doesn't have any effect.
The packages network-manager and network-manager-gnome don't contain init scripts at all, btw. Therefore I can restart Network Manager only by killing and restarting the processes manually.
The problem may be related to Udev, I suppose.
