Yes, with the new Ryzen 5xxx, the kernel 5.10.x is needed.


I have just replaced the CPU in an older computer, and in the first day I had to use the kernel 5.9.16, because in the beginning the kernel 5.10 was incompatible with the NVIDIA driver.

With the kernel 5.9, neither the ECC memory nor the CPU temperature sensors were supported.

However, the kernel 5.10.3 solved the problem with NVIDIA, then today I have upgraded to 5.10.4.

With these kernel versions everything that is strictly necessary works fine.

Nevertheless, extra AMD support is announced for 5.11 (e.g. PowerCap) and some monitoring features might appear in even later versions, so remaining forever on 5.10 LTS kernels on the new Zen 3 CPUs is probably not the best choice.

It is likely that complete and stable support for Zen 3 will be achieved only by the time of the next LTS.
