Hey, I think I am also affected by this bug. I run Ubuntu 15.10 on a Thinkpad yoga (first gen) with kernel 4.2.0-25-generic. When waking up after hibernating the screen goes completely black after entering the encryption passphrase. Ctrl+Alt+F1 does not work. I also can't change the Fn-Lock of the keyboard as indicated by a separate LED. I can only poweroff by pressing the powerbutton for some time. I will gladly supply any more information if needed.
