Public bug reported: Lenovo IdeaPad S540, 13-ARE AMD Ryzen 4800U, 16GB dual channel RAM, 13.3" 2560x1600 screen. Note this laptop is a lot like the Lenovo Slim 7, it seems this laptop UEFI Bios does advertise S3 sleep, the Slim 7 only advertises S2idle.
The errors are related to AMD Ryzen 4000 series. Clean (no dual boot) Ubuntu Budgie 20.04.1 with kernel upgraded to 5.8.11.
