AMD ryzen freezes linux

I know this quite common issue but cant to make it work properly. Then I use in machine learning tasks my PC just freezes, moreover the task is mostly GPU tasks and total CPU load in less than 20%.

Possible solution might be setting in Syslinux Configuration:rcu_nocbs=0-15 because the BIOS didn't have the "Typical Current Idle" Option.

1)

Anyway added to the grub options next things:

idle=nomwait

rcu_nocbs=0-15

GRUB_CMDLINE_LINUX="iommu=soft"

Nothing changed.

2) Deleted  files in .cache  and tmp - nothing changed

What can I do, update linux kernel, update BIOS, which is gigabyte and april 2018 version

.. and

-> System: Host: dex-pc Kernel: 4.13.0-45-generic

That is way to old kernel. Is not even the 4.14 LTS which has some backports..

Basically you'll need and 4.15++ best is to use 4.17..

This is not an amd or linux question. This is a known weakness of Mint in combination with Cinnamon and Nvidia.

Look here: https://www.reddit.com/r/linuxmint/comments/5pg2hf/cinnamon_crashes_with_nvidia_driver_with_181/

The best thing to ask in the Mint Forum: https://forums.linuxmint.com/index.php

I've had Ryzen CPU 5-1600 and 7-1700 on Gigabyte AB350N-ITX motherboard. The freeze issue I used to resolve raising a bit the CPU volts from 1.20 to 1.25 or to a max of 1.35.
Some people write to raise also CPU VCORE from 1.00 to 1.10.
Around there's lot of solutions altering C-State and so on, but it's related to power supply.
Or you change many psu till find the good and stable one, or tweak a bit with voltage CPU and/or VCore. It's important to prevent that CPU goes to a state where voltage is so low that a slightly unstable PSU is not able to achieve.

I've to say that upgrading to 7-1700 and new 7-3700X didn't freeze after last BIOS (>=F40) updates of that motherboard.

But installing back 5-1600 to do a small server with the same board resulted again in frequent freezes during few hours of idling. Impossible to make a server.

I resolved with that old trick to raise a bit voltage. 

The Power Supply is always the same a Tacens Anima 400W SFX.

@mechano: Would you please be so kind to describe how you adjusted the voltage?

I got a Acer Swift 315 Laptop which does not get any BIOS updates anymore I tried all max_cstate's between 1 to 6 with no luck. So I believe the theory of cpu/core voltage is too low is the cause for the freeezes...

Hope you can help me out.

Thanks in advance!

 

kind regards

Christian
