I have updated the bios (used WinToUSB to install Win10 on an external SSD, it works amazingly well). Unfortunately the error messages persist.
As the laptop does work (did not test 3D gaming yet, will do next week) I suppose I should just ignore the messages. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1897392 Title: Ryzen 4800u, kernel 5.8.11 boot errors (AMD-Vi, ACPI, HDCP, Bluetooth) Status in linux package in Ubuntu: Incomplete Bug description: Lenovo IdeaPad S540, 13-ARE AMD Ryzen 4800U, 16GB dual channel RAM, 13.3" 2560x1600 screen.
