Fixed how? There's the latest Agesa update you get from your motherboard vendor, should be Agesa 1.2.0.1 or 1.2.0.0 if they haven't caught up. I'd wait for the 1st week of April for the Agesa 1.2.0.2, that fixes some other bugs like USB ports not working, M.2's disappearing, PCIe issues and more. There's a chipset update on that site you can use to update you 550 or 570 chipset.
Those other CPU's used the "Ryzen Power Plan", discontinued for the 5000 series. That was the "driver" for those.
