I am affected with 16.04, kernel 4.4.0-51-generic.
The only way I could make my system work has been to install initial Ubuntu 16.04 and not upgrade any single package since installation.
I used to have hangs even before login, so I enabled auto-login without password and things got better.
I still have lockups during shutdown, so I need to hard-shutdown the PC every time, but at least the working sessions go smooth.
My system is an ASUS K550V, Intel Core i7-6700HQ, NVIDIA Geforce GTX 950M.
