Unfortunately there is nothing relevant on logs in a first sight; your theory is interesting, is it possible for you to give a try to Nvidia drivers? At least as a data point.
You could try "ubuntu-drivers devices" to show the latest nvidia driver supported by your device, and use it for a while, trying to suspend and see if it fails or not. Please, let us know the results.
