Hardware • Re: Crashes and freezes in Linux with (some) Ryzen CPUs

so I'm considering switching over to Intel.
It pains me to say so, but I'm leaning the same way, in thought anyway. I've been a staunch supporter of AMD since the 386DX40 which blitzed Intel's 486SX25. Similar situation when the Pentium came out and then all the way through to a few machines I have which have which have FX CPUs, including the awesome FX-8350 Black which is quite close to the Ryzen in everyday use, but just chews a lot more power. I built machines 10 years ago with FX-4350 CPUs that are still going strong. My notebook is a 7th Gen A9 and I even have an Athlon specifically set up for audio file work.

One thing I've done since my earlier post is to change the Global C State setting to off, rather than auto. I was getting occasional recurrences of the problem but since that change it has been absolutely rock solid. The only exception is Firefox which crashes repeatedly after running without problem for hours. Program crashes only, not desktop. Pretty sure this is just Firefox related though - doesn't happen with other browsers but I haven't really investigated it yet.
One thing I should've mentioned: when my computer crashes, the "CPU debug" light on my motherboard lights up (red). The same happens when I input incorrect memory frequency/timings (quick fix: CMOS reset). Do you also observe something similar?

So far, I've tried:
  • New DIMM sticks.

    New PSU.
The only culprits at this point can be:
  • CPU

    Motherboard

    Kernel
A colleague of mine using the 5900X doesn't have this problem.
