Same thing WAS on Asus U31Sg with kernel 4.4.0-21. I don't have this issue on 4.4.0-22 or 4.6.0. On the 2nd or 3rd suspend it freezes, no response from anything. All I can do is to hold power button to turn it off. This device has a HM65 Intel chipset. Some responses from here are related to video card, so, it has an NVIDIA 610M and I'm using it with nouveau driver.
