Title:
  Suspend doesn't work in ACER laptop

Status in linux package in Ubuntu:
  New

Bug description:
  I bought this laptop three years ago. Used Kubuntu 14.04 and 15.04
  without **any** problem. A couple of weeks ago I installed Kubuntu
  16.04 as always (formatting /root partition and doing a fresh install,
  not an upgrade). Since then both suspend and hibernation hang the
  laptop: the screen goes black, the laptop seems to stop but it won't.
  After a couple of minutes the fan can be heard and there is no way to
  restart linux. I have to power off the laptop (the hard way) and then
  turn it on. I have followed some threads and it seems that this is a
  common bug (it happens in several different hardware configurations).
  The original 4.4.0-22-generic kernel has been updated to versions 23
  and 24 (current) but no way. The bug is still present. Thanks a lot in
  advance!
