Upgraded to the 4.19.27 kernel but having stability issues

[zamlz]

Hi everyone,

I recently updated from kernel version 4.14.83 to 4.19.27 and have started to get stability issues.
Not really sure what is causing it but I know for a fact that X freezes up after a while (like a couple hours or less).

I have a hunch that it has to do with my AMD Ryzen 5 or the fact that I'm using Nvidia Drivers.
How would I go about figuring out where the issue is coming from?
I can also post both kernel configs if needed.

Thanks,
zamlz

zamlz,

Change something and see if the problem goes away.
If all you really did was a kernel upgrade, go back to the old kernel.

I suspect you changed more than you kernel. You must have rebuilt nvidia-drivers too as it provides an out of kernel module.
Did you update nvidia-drivers too.

If reverting to 4.14.83 fixes it. try a 4.16 or 4.17 kernel. Do a binary search.
Only change one thing at a time or you won't know what change had what effect.

On the basis that what you are seeing is a regression somewhere and it might be fixed in a newer kernel, you could try 5.0.x which is current testing.

I also had many issues with freezes with my Ryzen 1600 back when I purchased it. I changed my Power Supply Idle from auto and havent seen them since. Have a look at this link, maybe it will help point you in the right direction.
