    Ryzen 5000 CPUs and Ubuntu Mainline Kernel Installer on Ubuntu Desktop 20.04 LTS?

    Kernel 5.10+ is suggested for Ryzen 5000 CPUs. Would it be advisable to use Ubuntu Mainline Kernel Installer (with Kern 5.11) on Ubuntu Desktop 20.04 LTS, or am I just asking for trouble doing this?

    Ubuntu Desktop 21.04 is coming out April 22, 2021 so that is also an option.

    Let me know your thoughts,

    My personal choice in that situation (if the 5.8 kernel really is problematic for some reason) would be to use mainline on 20.04, then switch to HWE-edge when it gets the 21.04 kernel, then switch to HWE when that gets the 21.04 kernel. Then stay on HWE (which will eventually get the 21.10 and 22.04 kernels) until I get around to upgrading to 22.04.

    Installing 21.04 now is an option, but it's one for the adventurous, and means that you need to stay on top of upgrades every six months.

    I'm just a little reluctant using Mainline as from what I've read it's for testing/dev purposes. Overall, your suggestion sounds like a logical path to take. Thanks.
