Frequent Kernel Panics on new PC (Neptune HX99G)

GlowCat · 2025-07-25 16:42:01

I recently did a fresh install of arch on a minisforum pc and I noticed that its been having frequent kernel panics. I was originally running the zen kernel but recently switched to the standard kernel to see if that would help with stability but it still does not seem like it did. I usually run into at least one panic per day but the rest of the day everything else seems to be running smoothly. I believe the exact device model is the Neptune HX99G (and yes it should all be AMD hardware no Nvidia stuff in it) but I seriously feel like this is some sort of hardware issue since I have arch installed on 3 other devices and this is the only one that has Kernel Panics this frequently.

Last panic report:

Reinstalled system to see if it could have had some sort of setup issue but on a fresh install the issues still seem to persist with the system still having about 2 kernel panics per day.

it should all be AMD hardware no Nvidia stuff

Hey sorry I was gone for a bit I actually sort of found a fix(ish) by switching to the LTS kernel. I have not gotten any panics since switching and its been at least 24 hours since then.

In case the crashes return on the LTS kernel, see the ryzen troubleshooting article (that's a systematic HW issue)
If not, you should every now and then see whether this has been addressed in the main kernel because eventually the LTS kernel would update into the broken state.
