I've tested Mainline Kernels (Xenial) 4.4.8, 4.4.9, 4.4.10, 4.4.11,
4.4.12 and 4.4.13, all these works flawlessly suspend and resume a lot
os times with no errors. Mainline (Xenial) 4.4.8 works but lasts too
much time to suspend.

None of the Kernels in Ubuntu Xenial Repository worked.

Title:
  The system does not suspend on Ubuntu 16.04

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  When i try to suspend the system the screen turns off, the PC becomes
  really hot(the fan won't stop working) and i'm not able to do anything
  after this. The only option is to hard-press the power button to turn
  it off.
