Well, I have tested: ilya@thinkpad:~$ uname -a Linux thinkpad 4.8.0-040800rc4-generic #201608312129 SMP Thu Sep 1 01:31:59 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
Installation was smooth except the complaints about missing firmware---I dismissed these warnings. A new kernel hang after the very first reboot, but later worked flawlessly. Seems like the topic issue is *FIXED*. No traps after VT switching back and forth, multiple times.
