After confirmation that hibernation/resume worked well with sudo pm-hibernate, I enabled hibernatation on /etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla to get the option in the session menu. Unfortunately, every time I hibernate this way, the network devices are all set to unmanaged and I have to reboot to get them work again.
Strangely, this problem doesn't happen when I use the command sudo pm-hibernate or when I just suspend. Does the hibernate menu item use a different command than pm-hibernate? Or maybe with different options? How can I make it work properly?
