Host fails to resume from suspend when virtualbox installed

[silles]

Since I installed virtualbox my laptop fails to suspend to RAM properly.

Looks like it suspends, but when I open the lid it just reboots.

Laptop is a Dell XPS 13 9350 Developer edition OS: Ubuntu 16.10 / 17.04 Virtual box does not need to be running, just installed

Steps to reproduce:

• close lid and suspend to ram
• open lid and it will just restarts most of the time

From the logs: Suspending:

Let me know if more info is needed

I confirmed the bug by uninstalling virtualbox and managed to suspend/resume 10x times, no other changes were made.
