First of all, let me say that I've been searching and trying everything to solve this.
I bought an AMD Ryzen 5 3600 6-Core Processor CPU and a MSI X570-A-PRO about october/19 and just not work.
it freezes almost immeadiatly.

I've already tried:
- Turn of c6 trought scripts.
- Change MOBOs settings. Power Idle, Global Cstate management etc.
- Some kernel params:
- idle=nomwait
- processor.max_cstate
- idle=poll
- cpuidle.off=1
- Use other kernel versions, linux-zen, linux-lts

I've done a spreadsheet with possible combinations of all this params to check every single one, and nothing works.
I have the latest MOBO's firmware installed. All my system packages are also updated.
I already tried different distros, different BIOS versions, different BIOS settings.

The only way I found to not throw this machine window away was to set maxcpus=2.
One thing I've notice is that if I boot with all 12 cpus and run some stress application, system does not freezes. So I'm inclined to think that the "cpu waking up from idle" is the problem.

Does anyone has/had this problem too?
Does anyone had to manage it?

It's like almost an year since I bought a 6-core?/12cpu machine and able to use 1-core/2cpus. its very very very very frustrating.
No other distro works as well.
Windows cant reach Installation Wizzard after boot.

Thanks in advance.

Are you using BIOS 7C37vH9?
Under what condition the system freeze? Which test you run?

I'm attaching some kernel panic messages.
I'm pretty sure that is an Idle-management-related problem.
If I run an stress application (like prime95) on 1 cpu, i can stay live with the other 11.

Hi, I made a change that turn my system stable for week now. Here it is:
In CPU Ratio I changed from Auto to 36.00 (which is my CPUS base clock, 3600).
I'll mark this topic as closed. Hope it helps other people.

CYA
