[Kernel-packages] [Bug 1893624] Re: Ryzen 4800u, kernel 5.8.5 boot errors (AMD-Vi, ACPI, HDCP, Bluetooth)
Yes I figured that out, managed to uninstall and remove the default kernel (5.4) and the 'bad' one (5.8.5). Only 2 minor issues remaining: 1) Brightness setting is not persistent after reboot (it was with 5.8.5). When I turn brightness down using the quick keyboard button, it goes immediately to almost lowest, so the % of brightness is stored in the OS, but the screen itself booted with max brightness. 2) Hibernation does not work: $ sudo systemctl hibernate Failed to hibernate system via logind: Not enough swap space for hibernation Even though my /swapfile is 6.4 GB (40% of 16GB) and only 20% of my RAM is in use. Not big issues, since I can adjust brightness and I can use suspend. -- 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/1893624 Title: Ryzen 4800u, kernel 5.8.5 boot errors (AMD-Vi, ACPI, HDCP, Bluetooth) Status in linux package in Ubuntu: Invalid Bug description: Lenovo Ideapad S540 13ARE (AMD Ryzen 4800U).

[Kernel-packages] [Bug 1893624] Re: Ryzen 4800u, kernel 5.8.5 boot errors (AMD-Vi, ACPI, HDCP, Bluetooth)
It worked: via grub booted 5.8 and no more errors at boot. However, brightness setting is not persistent after a reboot anymore, screen is at max brightness after each reboot. If I modify it using the keyboard, it immediately starts at the lowest brightness. It's a minor issue. Not a big deal. I will stay away from 5.8.5 for now.
