I got the same error of Buttay on an Asus F3Jc:
I have to manually switch to ctrl+alt+f7 in order to see the graphical terminal and the network manager do not reactivate automatically the network, I have do click on it and do "enable network".
I have an external monitor attached to my laptop and in the second monitor before switching to the graphical terminal I can see those error messages:
i8042 kbd 00:04: activation failed
i8042 aux 00:05: activation failed
hub 5-0:1.0: over-current change on port 7
