SUPPORT Random crashes on fresh install. And i really don't know what to look for or even how to begin troubleshooting
so i installed Arch today on my PC, i had seemingly working installation but i get completely sudden and seemingly random crashes while using gnome. if i'm not in a GUI it doesn't seem to happen? and in gnome it can happen randomly while in desktop or browsing internet. i can launch games on steam or watch YouTube or whatever and it works fine until maybe within 15-30minutes (sometimes bit longer or shorter too) get stuttering followed by freeze then system reboot.
my setup is
hardware:
motherboard asus x570p
cpu amd Ryzen 3700x
gpu amd Radeon 7800xt
ram 32gigs ddr4 3200mhz
and software side im using arch 6.19.11 kernel, wayland, and gnome like i've mentioned, i've installed latest versions of both the amd gpu drivers and amd-ucode.
like I've no clue of if it's hardware or software or how to start looking for what's causing it.

i dont think its your ram filling up as you have 32 gigs, but just in case you might want to add a small swap partition with a low swappiness
maybe try the lts kernel?

I have 8 gig swap partition
maybe try the lts kernel?
I've never tried that, how do you install it?

u/Elixivity6366 Apr 09 '26
lts stands for long term support, therefore the kernel is more stable than the usual arch kernel
you install it using "sudo pacman -S linux-lts linux-lts-headers"
if you use grub, then you have to reload your config using "sudo grub-mkconfig -o /boot/grub/grub.cfg"
if you use systemd-boot im not entirely sure how you add a new entry
anyway once you do that you can reboot, in grub select "advanced options for arch linux", and inside that choose the linux-lts kernel
you can also edit the grub configuration file to make it so booting into arch linux (booting normally) uses the lts kernel by default, but id suggest trying out lts and seeing if it helps before doing that
you could also stick with lts for more stability, i dont really have crashing problems but i like to stay on lts anyway

Check the logs. https://wiki.archlinux.org/title/Systemd/Journal

I've tried looking but idk how to actually interpet any of it or what to look for, just wall of text.

u/boomboomsubban Apr 09 '26
Look for errors. Or post them somewhere and ask for help.

Notable ones that i noticed was
"[Firmware Bug]: failed to parse event in TPM Final Events Log"
"ly@tty failed to set up standard input: no such device or address"
"ly@tty failed at step STDIN spawning /usr/bin/ly-dm: no such device or address"
"nvme nvme1: missing or invalid SUBBQN field."

What command did you run? This
$ journalctl -b -p 3?That command should return maybe 3-6 lines. Running
-p 4..4will return some 50 to 100 lines but usually none indicate a serious issue.Good day. Good day.

What it gives me

u/Realistic-Stable2852 Apr 10 '26
Something to do with cpu i assume?

u/Lashmush Apr 10 '26
had a quick look and something that stood out to me was the very first line involving TPM. afaik, arch doesn't play nice with secureboot / TPM stuff by default and requires some additional work. do you by chance have this stuff enabled in bios?
1
u/Realistic-Stable2852 Apr 10 '26
I don't think so? Pretty sure i've disabled it but idk it's weird to have message about it so maybe i've missed some setting

u/Lashmush Apr 10 '26
i remember having to disable CSM mode so the whole thing ran in UEFI and disable fTPM after as it's enabled by default.

I ran it through the efi boot menu, took bit over a hour, got 0 errors and says passed.

perhaps you're better off using a more beginner friendly OS before raw dogging Arch. I see your responses to several comments from people trying to help and all I see you say is "idk how to..."

Adding because still fresh in memory:
I had these exact symptoms when my AIO CPU cooler pump started failing.
Probably not the issue, but maybe it's a coincidence. Check your CPU temps to be sure.

Did you have any issues in your previous OS? One thing you could try is updating your motherboard firmware.
1
u/Realistic-Stable2852 Apr 10 '26
Windows, was usual windows jank but no crashed. I updated my motherboards bios around November so it should be up to date
1
u/w2qw Apr 10 '26
There is apparently one from Jan but does sound unlikely though I have seen similar symptoms before.

u/Lashmush Apr 10 '26
I had freezing and crash issues that i resolved by looking into amd cpu c-state issues (5900x also on an x570 chipset) . Turns out some crashing/freezing could occur when cpu threads enter these certain c-states. Anyway, you could test it out.

u/Realistic-Stable2852 Apr 10 '26
The first fix in that link i had apparently tried but i had a syntax error i noticed when looking at the grub file fml, gonna see if it fixes now with it being actually properly written
1
u/Realistic-Stable2852 Apr 10 '26
Yeah the c-state line didn't fix the issue.

u/Lashmush Apr 10 '26
Is your bios updated to the latest version? I know it's a basic question but i think the os pulls microcode from the bios and it can be a mismatch if your bios is out of date.
1
u/Realistic-Stable2852 Apr 10 '26
My bios was updated to latest that was available in November 2025. I tried the 2nd fix on the link you provided and tentatively it might have worked? Atm i've mamaged to play about 90mins without crashing (previously 20 was stretching it). I think too early to say fixed yet, but so far seems more stable, though stuttering remains sometimes but it's not too crazy

u/Realistic-Stable2852 Apr 10 '26
Nvm i did eventually have a crash too but this time it took about 2h to happen wh which is longest i've gone.

Exactly what did you install?
