AMD GPU doesn't wake up from Hibernation

Hi:

I have an AMD R9-390 GPU, with a Ryzen 9 3900XT CPU, and an AMD X570 Motherboard. I think it started in F32, after upgrading a certain 5.8 version kernel ( think it’s 5.8.3?), my GPU just refuse to wake up from suspension. Like everything wakes up, except for the GPU and I don’t usually see any error messages either.

I thought it would get fixed in up coming kernel updates, but it did not … now I am on 5.10.12-200.fc33 , and the same issue is still happening … anyone has any clue why?

what gpu driver are you using? for me I use amdgpu and it needs a kernel parameter to disable the displaycode portion otherwise wonkiness ensues with power management and on my son’s pc, black screen on boot. (amdgpu.dc=0)
