AMD Announces Ryzen “Zen 3” and Radeon “RDNA2” Presentations for October

I recently bought a Ryzen 3900X. I hope Linux eventually supports these processors better. There has been some serious stabilization issues I eventually tracked down to being related to my processor. These issues required me to spend a significant amount of time researching. Things seem to just work with Intel processors. I'm hoping as popularity increases support for these processors will improve.

I've been running a 3900x under Linux since release (got it 14.07) without any issues. Support was great day one, but of course you needed a new kernel, not something that was running on your 2010 web server.

Linus has a Threadripper now - so it will be stabilized. :-)

I've been on Linux (mostly Manjaro, some Arch) with a 3900X for over a year, and I haven't had problems.

FC31 and FC32 on 3900x for half a year and zero issues either.

I suspect old kernels can be problematic. I had to upgrade past LTS to get my Ryzen 4700U laptop to even get video output.

I had 3900x on Ubuntu 18.10, 19.04 and 20.04 no problems whatsoever (Except with the nVidia GPU).

>serious stabilization issues

Care to go into more detail? I've just installed a server with a 3700X and the only issues I've experienced have been that I need a custom kernel module in order to get CPU temperature and power data (zenpower)

Is this on an old Ubuntu version or something? This was only true in the early days of these CPUs, which was last year. Temps have been working for a long time in the Arch world, but maybe it's different in point release hell.

I don't know, although I'm running the latest Ubuntu (20.04.1), with kernel 5.4.0-45-generic

It's been a while, so I have since forgotten the details... but I believe I needed to make a few changes to the BIOS to turn off idling or something like that.
