@ainar-g, right, dmesg will be useful. @Marius, could you try sudo apt install linux-firmware=1.187.24 to find the first bad version?
version should be 1.187.2[0-5]. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/1958283 Title: linux-firmware missing renoir_ta Status in linux-firmware package in Ubuntu: Invalid Status in linux-firmware source package in Focal: In Progress Bug description: [ Impact ] After today's update to the 5.13 kernel, my laptop's screen stopped working, showing random patterns instead. The laptop is ThinkPad X13 with an AMD GPU. In dmesg there was a message about amdgpu/renoir_ta.bin missing. Following some StackOverflow advice, I downloaded and installed linux- firmware_1.201_all.deb from the 21.10 repo, which has amdgpu/renoir_ta.bin and rebooted, which fixed my issue. Proposed Solution Add amdgpu/renoir_ta.bin to the current version of the linux-firmware package for 20.04 LTS. Additional Data $ lsb_release -a LSB Version: core-11.1.0ubuntu2-noarch:printing-11.1.0ubuntu2-noarch:security-11.1.0ubuntu2-noarch Distributor ID: Ubuntu Description: Ubuntu 20.04.3 LTS Release: 20.04 Codename: focal $ uname -a Linux ainar-ThinkPad-X13-Gen-1 5.13.0-25-generic #26~20.04.1-Ubuntu SMP Fri Jan 7 16:27:40 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux [ Test Case ] See above. Kernel log shows firmware load failures for amdgpu firmware in combination with the OEM 5.13 kernel. [ Fix ] Kernel fixes for new amdgpu firmware have landed in linux-oem-5.13 so it's now safe to update amdgpu firmware on focal to match impish.
