Ubuntu – System freeze after suspend

Since I installed Ubuntu 16.04 my laptop (HP Probook 450 G2) has issues waking up from suspend. Rarely it manages to properly wake up from suspend, but mostly the screen either stays black or it turns on, and completely freezes after 2 or 3 seconds, followed by a bit louder fan activity in both cases. I cannot switch to a tty shell, or do anything else apart from killing the power by holding the power button.

I tried following different solutions such as disabling USB Legacy, adding acpi_backlight=vendor acpi_osi='!Windows 2013' acpi_osi='!Windows 2012' to GRUB_CMDLINE_LINUX_DEFAULT, but nothing worked.

I switched to Linux Mint yesterday just to test if I have an issue there, but it still persists. Here is the output of /var/log/kern.log which shows the last messages from my previous session.
