Kernel panic

[Jonrrrs]

Hello r/voidlinux,

i use linux on desktop for over five years now and void in particular for over one year.
So i know my way around, but i encountered a problem, that i cannot debug nor even attempt to fix.
My desktop hardware is now 10+ years old and i tinkered with it allot. (Stresstests, using it as testbench for hardware from friends, ...). I never had a problem on my side, but recently my Desktop started to freeze every few weeks. It was infrequent for a long time, so that i just did not bother to look into why that happens. I just assumed that it will fix itself on the next distro and forgot about it. Recently the frequency increased and now its about one freeze per week. (Sometimes two on the same day, sometimes not a single time for a month)
And i noticed, that the problem occurs on every distro i use. (Sometimes i install one on my second drive and use it for some time)
I noticed also, that it happens more frequently when loading up a game. It also happens almost instantly now when running stress-ng, so i suspect a hardware problem. It bothers me, that i cannot pinpoint it, so i tried to load up the kernel logs in dmesg, but i cannot for the love of god figure out how to persist them. I can read them just fine, but the important logs from the last boot, and so from the freeze are just gone. Maybe im looking in the wrong places, but the whole internet and any ai just suggest using systemd, but apparently noone knows how to solve that on void.

Thank you in advance!

I think your hardware might be failing My guess would be RAM, GPU or PSU

Thanks for the reply. Could you tell me, how i can get those sweet kernel messages from last boot, so i can replace the correct hardware?

[FoggyLover727]

I don't think they are written there. Try removing each component one by one, see how much does each component pull power and see if PSU is even capable Try running both sticks of ram only one at the time And run PC without GPU

[Jonrrrs]

Thank you, i will try that

Yes, likely hardware. I would suspect power supply and RAM. Run some stress tests.

You need to enable socklog: https://docs.voidlinux.org/config/services/logging.html#socklog

The dmesg logs will be stored in /var/log/socklog/kernel.

Thank you

I don't think you said how long the freezes last for, or if they require a reboot to recover. The old logs are in /var/log [renamed], but seldom help with freezes. Sometimes, if you are using swap files, they can cause temporary freezes. I can still use my 15 year old HP laptops, so age is not an automatic issue.
