Help troubleshooting OS freezes

[mrichetta]

Hi everyone! ~2 years EOS user here.

Context

I started using hyprland 3/4 months ago. It worked fine until recently.
A while ago, like 4 weeks ago, I started experiencing some OS freezes.
I couldn’t find any patterns or programs to blame for this behavior. I’m not sure if it’s a resource issue, a specific software or maybe hardware.

I’m suspicious of vscode or chromium => Electron?

What I tried

• I switched to KDE (Wayland) thinking it was a hyprland issue, but I still got freezes.
• I switched to KDE (X11) and it’s still happening.
• I increased the swap memory from 8 to 16 GB, but according to btop the swap memory is hardly used

Logs

I read https://discovery.endeavouros.com/forum-log-tool-options/how-to-include-systemlogs-in-your-post/2021/03/ and I leave the logs below.

• Hardware (inxi -Fxxc0z): https://0x0.st/XFwF.txt
• Boot (journalctl -k -b -1): https://0x0.st/XFxo.txt

Can you help me troubleshoot?

Thanks

There is a critical bios update for this laptop. Maybe start with that.

version 7WCN38WW 07 Jan 2020

[mrichetta]

Okay.
First, I ran pacman -Syu to get the latest software updates.

After searching about Lenovo BIOS update, I found this page https://support.lenovo.com/us/en/solutions/HT510810-HOW-TO-DO-SOFTWARE-UPDATES-LINUX

This led me to run fwupdmgr get-updates. Logs here

Posting before I update.
Update: that was fast.

[ricklinux]

I don’t have much experience or exposure to fwupdate. Lots of people do use it but I can’t say much about it. Hope it goes okay without issue.

Edit: I see the log shows the version it has but i don’t see that it shows the updated version but then again maybe that command doesn’t.

Me neither. First time I use it.

Do you see any visible error on journalctl logs? I don’t have much experience reading them, not sure about what to look for.

On the other side, I found some issues between AMD Ryzen 2500u and freezes

• https://bbs.archlinux.org/viewtopic.php?id=250297
• https://www.reddit.com/r/linuxhardware/comments/afktfv/linux_freezes_and_amd_2500u_chipset/

So I’m trying with this option. I’ll report back.

[ricklinux]

Do you have Windows on the Lenovo?

[mrichetta]

No, just Linux.

[ricklinux]

With the Ryzen 2500 you may need to try some kernel parameters such as

idle=nomwait

Not sure if you are using grub or systemd-boot because it’s different to add them. This is just one that I’m guessing at trying. There are others but need to think which ones would be likely candidates.

Edit: Another one to try is

processor.max_cstate=5

[mrichetta]

Great. Just made a little search a found about that param EndevourOS randomly freezing - #5 by buffy

Going to update it now.

[ricklinux]

Are you using systemd-boot or grub? Do you know how to add them correctly and run the appropriate commands?

[mrichetta]

Followed the instructions in that post.

EndevourOS randomly freezing

In the article already linked (https://archived.forum.manjaro.org/t/amd-ryzen-problems-and-fixes/55533) above: Kernel Boot Parameter Adding a kernel boot parameter for GRUB in Manjaro: Open the file /etc/default/grub in a text editor. Add the parameter, in this case idle=nomwait (notice the m), to the line starting with >GRUB_CMDLINE_LINUX_DEFAULT=, at the end, within the quotes, like so: >GRUB_CMDLINE_LINUX_DEFAULT="<current parameters ...> idle=nomwait". Save the file. Update GRUB: sudo u…

I think I’m using grub.
UPDATE
Amazing, it seems I’m using systemd

> [[ -d /run/systemd/system ]] && echo "using systemd" 
using systemd

> ps 1                                                 
    PID TTY      STAT   TIME COMMAND
      1 ?        Ss     0:02 /usr/lib/systemd/systemd --switched-root --system --deserialize=47

I’ll try to change to grub.

[ricklinux]

No don’t do that!

Edit: Just add the kernel parameter to /etc/kernel/cmdline and then run sudo reinstall-kernels

[mrichetta]

Thanks for the advice. I’ll add the kernel parameters.

I thought grub and systemd-boot were interchangeable, but it seems I have some misunderstandings.

[ricklinux]

You can switch to grub but it’s not necessary and if you don’t do it correctly it’s just going to be another headache you don’t want or need.

[ricklinux]

Hopefully it works for you. If you still have issues try adding the other one along with it with the same procedure over again. These are the only two that i can think of that may help.

processor.max_cstate=5

[ricklinux]

@mrichetta
Well did you get the kernel parameter added? Has it made any difference?

[mrichetta]

Yes, I added the parameters to /etc/kernel/cmdline as you suggested.

After booting, I can see the current boot cmdline

❯ cat /proc/cmdline
initrd=\6b566fe848454b72b9a0579ca00a3a98\6.12.4-arch1-1\initrd nvme_load=YES nowatchdog rw root=UUID=4a19720e-042f-48d9-80ef-3b5c83d35842 rw root=UUID=4a19720e-042f-48d9-80ef-3b5c83d35842 iommu=pt idle=nomwait processor.max_cstate=5 systemd.machine_id=6b566fe848454b72b9a0579ca00a3a98

So far, so good.

I’ll have to use it for work today. If tomorrow is still working fine, I’ll close this post as solved.

I have the same problem with the same laptop, but with another processor, which is the Ryzen 3 2200u.
The problem appeared only a few days ago, after updating to Mesa 24.3.1 or kernel 6.12.4.
By the way, I am on pure Arch with KDE Plasma

You mean you have an Arch installed system.

I hope it solves the issue for you.
