Unfortunately, nothing has changed.
As for now only calling pci_save_state() makes system usable on return from S3.

Thank you. I just finished testing all three variants and none of them
solve the problem.
This time I used second computer to login via SSH and grab dmesg logs.
Problematic part always begins with this line:
nvidia :01:00.0: Refused to change power state, currently in D3

If this is not a problem for you, I would ask for binaries.
Both threads contain different versions of patches and I don't know if I
should take exactly that ones from the messages you are linking to or
the last available.
Thanks in advance!

Attached dmesg log shows S3 suspend and resume cycle on my machine with
pci_save_state() enabled. From my point of view it looks pretty normal
and fully supported.

435.21-0ubuntu2 from official eoan repository.
When this patch is removed from dkms.conf, after recompiling driver and
updating initramfs suspend/resume works as expected.

Bugs,
Correction - when I boot 5.3.0-13 no Nvidia proprietary driver is
loaded. That's why the bug does not appear here.

Title:
'gpu has fallen off
Public bug reported:
With this message the only way to resume work is to reboot the system
using power button.
With kernel linux-image-5.3.0-13-generic everything is OK.
Problem appeared afer upgrade to linux-image-5.3.0-17-generic and still happens
in linux-image-5.3.0-18-generic.
After update to version 15.04.0, platform KDE 4.14.7 drag and drop
adding works OK. Adding by right click menu Add to places works until
Dolphin restart. Thanks!

After yesterday's system update plasma runs smoothly only ~2 minutes.
After that kded5 eats all ram and swap file and freezes the system. I
had to switch to openbox which is a real pain.
