Nonstop system freezes/crashes since switching to AMD

Quoting: brokeassbenI've tried this out and haven't had any crashes after a couple hours of gaming, which makes me cautiously hopeful! I'll try a few more games after work today to see how it goes. My hopes have been dashed a few times with other attempts at fixes.
the fixed I mentioned is a hardware bug that Ryzens have. On Windows it's patched at microcode firmare level, on Linux it _should_ be patched as well, but seems that Linux kernel devs haven't completely nailed it and sometimes it can happen even with patches.. it would make sense, that might be the reason why you don't experience the bug on windows, on windows the microcode patch works better.

Try disabling core boost and precision boost in your bios.
Run your computer and see if it crashes.
I have a similar problem with my system, the motherboard for one reason or another isn't managing the voltages properly.
And stock overclock (core boost and precision boost) were on by default.
Guess it could also be the cpu as well, but I found killing the motherboards stock oc fixed the problem for me.

Your problems sounds a lot like what was reported in this rather big thread: https://www.gamingonlinux.com/forum/topic/4128

It may not be a client-side problem. Like @The_Aquabat is also inferring.
Well shit. It had a few hours of stability followed by several freezes. Briefly thought that @TheAquabat had the answer with this:
Quoting: The_Aquabatprocessor.max_cstate=1 rcu_nocbs=0-23 idle=nomwait
or
processor.max_cstate=5 rcu_nocbs=0-23 idle=nomwait
Thanks, though. Here's my dmesg output in hopes somone can see something obvious I'm missing:

Got a crash within about 5 min :(

Quoting: Liam DaweI would seriously suggest checking the RAM. Most of the time this is a RAM problem.
Tried dropping the RAM to its base frequency as well as max. Sorta took your advice and am replacing the RAM out of desperation for a stable computer. It's been a frustrating experience.

the dmesg log you posted doesnt have anything weird except your drive is failing..ext4 errors

Ouch, didn't even think of that. A failing drive could even be an issue.

That might explain why Windows is stable since it can't mount that drive. Might also explain why Steam's shader caching will hang for hours at a time. After several years of help desk work, that should have occurred to me 🤦‍♂️ Also just dawned on me that I've had the two platter drives in three different computer builds since 2013 and they've gotten A LOT of use. SMART reporting shows OK health, but several errors including many marked as "pre-fail." Well I feel like an idiot. Going to disconnect the drive and see if that solves all of my woes.

yes, right, a failing hard drive can produce similar sympthoms, random reboots hard freezes, but you would normally get something from dmesg telling that there is an I/O error on the drive.
are u using journalctl? u could check on the next boot after a failure with

journactl -b -1
