  Ubuntu 16.04 Xenial hard crashing on ACER E3-11-P0D8

Status in linux package in Ubuntu:

Bug description:
  About a month ago I installed the latest Ubuntu 16.04 Xenial on my
  ACER E3-11-P0D8 laptop. Since then, it randomly freeze up while I
  work. It generally takes 10-20 mins to do that.

  Out of frustration, I started to change the kernel. It seems that
  every >4.0 kernel is freezing up my system. Now i am stable at 3.19.8
  from here: http://kernel.ubuntu.com/~kernel-ppa/mainline/

  Please note: When using old kernel ( 3.19.8 ) i have no crash. But
  when i use the latest one, it freeze up and i can not use anything (
  no kernel panic, no terminal, nothing, keyboard mouse doesn't work ).

  The freeze happens very randomly. It can take 5 mins or hours after
  working. And it takes me to switch off the laptop and start it again.
