Hello Salvatore, for AMD Ryzen and AMD Renoir hardware support, the Debian kernel "master" branch still has one commit that is not merged into the "sid" branch until now. See this for details:
https://salsa.debian.org/kernel-team/linux/-/commit/4bc3f848e6e5b491047b5e298d6cf9ae7b85727a Would be great to get this merged into 5.9 Debian kernel releases and not have this pushed out to 5.10 Debian kernels. It only enables further kernel modules, so should be real save. best regards, Florian La Roche
