It can be easily reproduced by trying to press the "logout" button. The system would immediately hang. Reverting to previous kernel, 4.8.0-22.24 fixes the issue. My hardware is a Dell XPS 13 laptop, model 9343. It has the Intel HD graphics card, using i915 module. Description: Ubuntu 16.10 Release: 16.10 Thanks!
