Keyboard is totally dead. Nothing else than hardware reset is possible. This bug affects normal, upstart and recovery boot. I don't know whether that is a kernel panik (no led is blinking) or the driver for keyboard is failing. boot.log looks normal to me. Last and working kernel version before the update, was "Ubuntu 4.4.0-34.53-generic 4.4.15". I cannot report "ubuntu-bug linux", because I cannot enter the system. I am willing to investigate, but please give me hints.
