Laptop randomly freezes, looks related to the network stack

This is a system76 gazelle, I've dropped their pop os and installed arch.

Initially I had gpu issues but disabling the laptop monitor (using external monitor) and setting the power profile to battery has "solved" it.

Now I can't sort out the other crash I'm having. It happens quite randomly and not too often. I can use the laptop for a few days without having this crash, even though once or twice it has happened not too long after booting.

Running journalctl -b -1 on rebooting after the crash, this seems to be it: https://pastebin.com/Egaa6Kwj

Any help?

Re: Laptop randomly freezes, looks related to the network stack

Do you have any concurrent network services?

find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f

, also in doubt limiting to just kernel logs or just the dump might loose relevant context and it'd be better if we had a full journal's worth of output to be able to identify potential correlations.

Thanks for the reply. I don't think I have any concurrent network services, here's the output: https://pastebin.com/raw/gPff17Di

I don't have the entire journal now, I'll see if I get it next time, but I remember looking for something that could've been logged before the crash and there was nothing.

I actually just had a quick freeze that lasted 2 seconds and didn't require me to reboot, and journalctl/dmesg show these network related errors.

journalctl --since today: https://pastebin.com/Pbc7N2Vc
dmesg -T: https://pastebin.com/xBUP3e7R

Seems to be the same error, but didn't require a reboot this time.

Re: Laptop randomly freezes, looks related to the network stack

It's kinda freezing more than before, and it's not always requiring system reboot. And it's not always that random, sometimes it seems triggered by something I run that requires the internet, for example running a git command.

I've looked around (web and llms) and some say it could be related to power saving mode. I'm on system76-power battery profile, so that could be related. But if I leave battery profile I'm probably going to get gpu-related crashes --- hard to test.

I'm on system76-power battery profile, so that could be related.

https://wiki.archlinux.org/title/Power_ … interfaces - but obviously you want to *disable* power saving here.
