It sure sounds like there are some other patches in Ubuntu's kernel causing problems.

Could you check mainline v6.9 and v6.9.7? I know they backported some ASPM patches. Maybe those cause issues for some of these machines?

If those are fine then what I suggest doing is bisecting Ubuntu's kernel tree, specifically with your test being "echo mem | sudo tee /sys/power/state" to suspend the machine and making sure GFX is otherwise idle.

This will ensure you're not hitting the issue of the race condition mentioned in the description while doing the test.

Here is the Ubuntu kernel tree:
