AMDGPU fails to resume from suspend
Brief summary of the problem:
The display always remains off after resume, no signal is detected on any interface. In case of hibernation, the system boots normally, then the display turns off immediately after reloading the saved state. I tested with multiple kernel versions, the error is same (6.3.x-6.4.x)
