Is it just me or did network-manager(-kde) die over the past night:

Hibernate a fully functional networked maverick. On wakeup: the OS decides to reboot instead.

On that first reboot I get an fsck but nothing at all onerous I'd say. On log in: network manager says that it's been disabled. Rubbish, says I: checking iwconfig/ifconfig reveals my wired & wireless network devices are down. Odd, they should be definitely _up_. Reboot: not fixed. Plug in an ethernet cable: no luck. Boot with an ethernet cable attached to a rootprompt with networking (from the recovery options) I am able to update the system. Reboot normally with ethernet cable attached: I have internet. Reboot without the ethernet cable attached: network manager is off to play games again. Try a few radio rfkill switches: dmesg | tail reveals that these register with the appropriate power management hook (and I get a warning about unknown key being pressed) but network manager doesn't notice anything. Reinstalling network-manager & network-manager-kde from the rootprompt with networking doesn't fix it either.

Give up and install wicd-gtk from the rootprompt with networking (after plugging in the ethernet cable again) -- everything is fixed now.

Any ideas?

I would have filed a bug before installing wicd-gtk. That way the information would be from the correct configuration for your box.

This happened to me on my Arch Linux machine a few days ago, and I found the solution here: http://bbs.archlinux.org/viewtopic.php?pid=728494

Basically you need to stop NetworkManager, delete /var/lib/NetworkManager/NetworkManager.state (or whatever the Ubuntu location is) and restart NetworkManager.

Thanks: that did the trick. Removed the file, reinstalled network-manager-(kde) and purged wicd and its gtk/cairo dependencies.
