Crashes and freezes in Linux with (some) Ryzen CPUs

No, I think you miss the whole point. The components are not faulty, it's just that the CPUs won't run Linux reliably. That is fairly well documented on the web.

I don't know about "the web", but nothing what you said in this thread has confirmed with 100% certainty that your CPUs were responsible. You have not exhausted necessary troubleshooting steps, so you will never know what was the culprit.

Forgotten already?

Did you used your search engine to find it? I did, and there is plenty of answers and solutions.

Nothing THAT I've said?


Donated one of the motherboards and CPUs to my sister and bil who've been running Windows on an FX-4350 that I built years ago. Apart from the massive performance improvement the system is rock solid stable, again confirming that it is an issue with the CPU and Linux. How do I know that? Well, I installed Debian as well, on a dual boot setup and guess what? Yep, the stability issues are immediately apparent when running Debian. Not a problem for them, since they're Windows devotees and won't ever even boot into Debian.

Yes, plenty of answers and typical solutions how to troubleshoot a PC with a problem. Nothing about your CPU being broken completely on Linux. But maybe such reports are there, I don't remember now, it doesn't matter. Anyway, you should have investigated it when you had a chance, to discover that bug causing this, maybe motherboard BIOS, maybe something else, it's too late now.

Found this thread from your comment elsewhere. This appears to be a solution to your problem:

Recording solutions here too:

- Update BIOS and set PSU Idle to Typical Current Idle
- Kernel parameters for both your computer and all Virtual Machines running on it: idle=nomwait processor.max_cstate=5

This seems to have solved the problem for other Ryzen 1000 series owners. Maybe it will solve for you as well?

Thanks. Some of that I knew but some is news to me, even if a bit old (2020 and Debian 10 and before my CPU was even released). It is, or may be, relevant, though.

At the moment the Ryzen motherboard and CPU is packed away but I'll probably get another case or two and rebuild. When I do I'll try the suggestions you linked.
