[Paul Ortyl <1429622@xxxxxxxxxxxxxxxxxx>]

Background information: the main problem is the nvidia driver.  I have also freezes at boot with the last line stating ACPI: Video Device ....   Unfortunately with this hardware I cannot use builtin  Intel GPU because it does not drive any of external video ports.
I have two 3K monitors connected over docking stations DPorts , lid is closed. 

I tried all 3 version of nvidia binary driver available through packet manager, none works properly in context of suspend/hibernation.
Suspend/Hibernation never worked reliably. I have managed a few times to wake the system from hibernation, but it was very rare.

As this issue being fixed is very important to me, let me know how can I
help further.  I would be glad to test any hint or workaround you
provide.
