Finally after upgrading today to Ubuntu Kernel 4.4.0-28.47, equivalent
to Mainline Kernel 4.4.13, suspend/resume works out of the box, no
special kernel parameters nor rc.local commands needed.

ATI discrete graphics starts DinOff but can be used when desired.

Title:
  [HP Pavilion dv6-6b52sl Entertainment Notebook PC] No suspend on
  Ubuntu 16.04

Status in linux package in Ubuntu:
  Confirmed

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.
