This is a nouveau issue. Unload nouveau and hibernation start working normally again.
Ctrl+Alt+F1 sudo service lightdm stop sudo modprobe -r nouveau sudo service lightdm start
Btw, how is it possible that system works completely normal after unloading nouveau ? Is it safe to do apt-get remove xserver-xorg-video-nouveau ?
