I have a Ryzen 3 1300X at the moment and it’s always had this soft lock freezing bug on Linux. I used to dual-boot Windows on this machine and Windows never had the same problem, so I think it is an issue with the Linux kernel (I’ve also replaced nearly every bit of hardware that I originally built the PC with, except for the CPU and motherboard, so it probably is an issue the kernel has with my CPU, or possibly the motherboard firmware).

I’ve changed the kernel parameters as suggested by the Arch Wiki. The bug is pretty inconsistent about happening so only time will tell if this solves the issue. But if it doesn’t solve the issue, I’d honestly consider just getting a new CPU that doesn’t have this issue, as completely freezing up, unable to get to a tty or anything, and only being able to power off by physically holding down the power button, is a pretty major issue, even if it only happens sometimes.

So if I do get a new CPU, or maybe just for when I’m next buying a CPU for reasons unrelated to this bug (been considering an upgrade to something that’s better for compiling anyway), are there any good options out there? Intel is investing $25 billion into Israel and the BNC has called for “divestment and exclusion” from it (it’s not officially on the BDS consumer boycott list, but I’m still very much not comfortable buying from Intel). But the Arch Wiki article seems to suggest this bug is applicable to Ryzen CPUs in general, or at least it never specifies a particular model or range of models. So maybe I’m limited to non-Ryzen AMD CPUs?

I’m guessing this is one of the situations where two companies have a complete duopoly over the market and there isn’t an all-round good solution, but thought I’d ask in case anyone had some useful input.

    I had a similar problem with a Ryzen 5 1600, at first it worked flawlessly when I did a manual OC, then when I made a reset, I didn’t care to OC again, and it began to occasionally freeze, usually when idle. When I made my manual OC again including upping voltages a bit for CPU and RAM it worked flawlessly again???

    Weird since motherboard defaults aught to be stable IMO, but apparently they aren’t always.

    I’ve been using this CPU for 7 years now, and it still runs like a champ, as long as I don’t use the motherboard defaults. I can’t remember last time it crashed or froze.

    EDIT:

    I just found out the package “disable-c6-systemd” mentioned in your link, is exactly to prevent voltage drop below 1v at idle, which sounds exactly like the bug I had. which is funny to learn 7 years later. ;)
