Re: Updating microcode files didn't help, maybe a kernel problem after all

I will likely be doing a remote installation onto an AMD Ryzen 7 2700X
3.7/4.3GHz in a couple of months.
Accordingly, I took interest in your post.
Although the kernels that I build are Reiser4 -enabled and I have not
created yet the netboot for my project, I have done a preliminary
build of a kernel 4.14.21.

You are welcomed to give it a spin as it will also support the other
usual filesystems. In your case, you do not have to do anything
special as you are not running reiser4. Hence just
[sudo] dpkg -i linux-image-4.14.0-3+reiser4.0.2-amd64_4.14.21-1+reiser4.0.2_amd64.deb
from (URL link on a single line)
< https://sourceforge.net/projects/metztli-reiser4/files/Ryzen_Reiser4-SFRN-4.0.2_Linux-4.14.21-1_Stretch-bp/

might suffice.
If it works and you like the 'Debian way' of building kernel packages,
I will provide you some guidelines -- based on your feedback for your
own customization -- so that you can build your own kernels for Ryzen.
