Ok I now had access to the AMD laptop in question, and it has oem- sutton.newell-abeeku-meta.list pointing to sutton.newell repository.
I can also point out that additionally 6.8.0-40 itself does not fix the flickering, it improves the situation but does not fix it. And as mentioned, linux-oem-6.8 is not available in the Ubuntu 22.04 repositories, and Lenovo as a vendor has LTS upgrade disabled by default. ** Also affects: oem-sutton.newell-abeeku-meta (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-oem-6.5 in Ubuntu. https://bugs.launchpad.net/bugs/2070096 Title: [amdgpu] Graphics driver issue: Display goes black for a second at random: [drm:link_enc_cfg_validate [amdgpu]] *ERROR* link_enc_cfg_validate: Invalid link encoder assignments - 0x1c Status in linux-oem-6.5 package in Ubuntu: Won't Fix Status in linux-oem-6.8 package in Ubuntu: New Status in oem-sutton.newell-abeeku-meta package in Ubuntu: New Bug description: After some update my display randomly goes black for just a second and comes back.
