I just upgraded to a 3rd gen Ryzen processor for rendering and I can't monitor CPU temps. Apparently, support for this is added in Kernel 5.4. Update Manager says the system is up to date, but I'm on 5.0.
Articles online mention "mainline" but say it's not for production use. How can I get an official/production/stable 5.4 kernel on 19.3? (besides "wait for the next OS release").
