  [Acer Aspire ES1-411] Ubuntu freezes occasionally

Status in linux package in Ubuntu:

Bug description:
  I am running Ubuntu 16.04 and my notebook freezes occasionally. I am
  running Ubuntu on an Acer Aspire ES1-411 (P6B1).

  There's also an identical Bug filled with Acer Aspire ES1-311 and both
  Ubuntu 15.04 & 15.10 by Christian Wansart here:

  I have no clue what causes this, my system just freezes and I can't do
  anything anymore. When it  happens, I have tried the following
  secuence without any luck, I have to power down manually:

  1. ALT + F2, type xkill + ENTER. 
  2. Press Alt+Ctrl+F1.
  3. While holding Alt and the SysReq (Print Screen) keys, type REISUB.

  Last time I was only viewing a Youtube video using Firefox. I checked
  some log files but I couldn't find anything suspicious.

  Any ideas?
