Any source on this claim? Care to elaborate with any specifics? I have not ever heard of any issues with Linux on Zen architectures, nor have I experienced any on either of my Zen 2 machines.

I purchased a first gen Zen CPU around when they first came out and noticed a lot of random issues on Linux that often resulted in full system crashes; usually due to C-State stuff and other times due to various motherboard firmware issues that only Linux users seemed to experience. They didn't take too long to get fixed but you needed the latest versions of the kernel to keep up with them. However other than those first few months my experiences match yours and I have experienced zero issues. I could see it being possible someone possibly still using an older version of the kernel would still experience these issues, especially if they haven't flashed their bios.

My laptop is an AMD Ryzen 5 2500U. Plenty of issues starting from the installation. I had to stop the installer from booting, add this hard to find line: ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2 to the kernel load line, just to be able to install it. And then, after finally managing to install it, the stability issues. Even with the latest Liquorix kernel, after some hours, the system just kept randomly freezing. It was a total infuriating experience. And I was not the only one with these issues: https://www.linuxquestions.org/questions/linux-newbie-8/can%27t-install-linux-on-ryzen-5-2500u-4175650046/ https://www.linuxquestions.org/questions/linux-newbie-8/can%... https://bbs.archlinux.org/viewtopic.php?id=250297 https://bbs.archlinux.org/viewtopic.php?id=250297 I nuked Linux, and now the machine runs only Windows. And it works fine. No more randomly freezing. That's what I get for being an AMD fanboy and an early adopter. I'm glad you have the latest Zen processors, I am not so lucky.

  Latest would be Zen 3 or Ryzen 3000 series. I've got Zen 2 chips, Ryzen 2000 series, same as you. yesco's comment above yours is probably useful here - I can definitely believe there were some issues with Ryzen when it first came out. How long ago was this and what kernel version were you using? The links you posted seem to reference Linux 4.x and 5.1. If you tried again with some recent 5.8/5.10 kernel I bet you'd see a marked improvement. Linux moves quickly and support for new hardware is generally established early, though not without initial bugs ;)

    I tried running Linux for one full year, since I got the laptop, until I got fed up. Even if Linux in Ryzen works flawlessly now, I got an Intel laptop from my employer and that one has all the Linux stuff. Another honest review of issues with Ryzen, hopefully he is someone you can believe: https://youtu.be/Fmj2kUk-xO4 https://youtu.be/Fmj2kUk-xO4

      I don't disbelieve you, nor am I attempting to invalidate your experiences. Just trying to express that as valid as your experiences are, equally valid is the fact that the issues you experienced are no longer present.
