had the same issue, fixed with newer mainline kernel
Ubuntu 16.04 xenial Intel Core i7-3520M CPU @ 3.6GHz x86_64
using repo HWE kernel (linux-image-generic-hwe-16.04): 4.13.0.36.55 ---> hibernation broken
using mainline kernel (linux-image-4.15.9-041509-generic): 4.15.9-041509-generic ---> hibernation works
how to install (bc people asked and I don't want to clutter bug report): https://pastebin.com/3Cg4jeeH
