I have assembled my desktop PC about 2 years ago. It’s fairly beefy (AMD Ryzen 9 3950X 16-Core Processor, 128Go RAM, nVidia RTX 3080 Ti). It’s running debian stable.
Once in a while (not that often, but like every 2 weeks or so), seemingly at random times, not especially under heavy loads, the system crash and freeze, irresponsive to even the linux sysrq magic keys. I never manage to find what was the cause. One interesting fact is that when it happens, for some reason it seems to “freeze my network” too, ie, other (ethernet) devices on my local network have no connectivity anymore. They’re all connected to the same router, but not through this crashing PC. Connectivity comes back as soon as I force shutdown the crashing PC.
What can cause this and how could I fix these freezes?
Uninstall (I don’t know how, on debian) NetworkManager and reinstall it (better get a .deb)
Then
sudo systemctl enable NetworkManager.serviceReboot and hope for the best.
This has been happening for 2 years, with the previous debian version too, so I doubt this would do anything?
If its been happening for multiple years and os’s, maybe your network card is dead/dying? Buy a new network card and see if that helps?
Everything is 2 yo, so this would mean the mobo (well, the onboard ethernet thing) was malfunctioning from the start. Maybe!
I might try disabling and using the onboard wifi chip temporarily instead, just to see if I notice a new freeze. The issue is, I’ve never understood what triggers it, and it’s quite rare (less than once a week), so it’s really annoying to debug…
Have you been updating or reinstalling ?
Parce que si c’est update sur update ça pourrait venir de là. Dans ce cas réinstalle peut etre ?
Updating. I’m willing to try your solution but I am a little bit worried about not being able to reinstall anything after I
sudo apt remove network-manager. Why would a package reinstallation help? Wouldn’t resetting the config files be more efficient btw?EDIT: Ce n’est pas update sur update, y a juste eu bullseye (d’abord testing, puis stable), puis récemment je suis passé à bookworm. Mais le soucis est là depuis le début. Il est pas trop chiant parce que c’est rare, mais quand même ça m’enquiquine.
Thing is, I really haven’t used debian based distros for the better part of the last two years so I’m not sure how to reinstall it if something goes south. With arch you just have to do a pacstrap with a liveUSB.
So… it seems kinda dangerous if you don’t have a backup .deb. I’m not sure I would advise you to go this way.
I looked at your journalctl. The error might come from your wireless card. If that is the case, and since you don’t use it at all there is a simple trick :
sudo systemctl disable wpa_supplicantthen reboot.It won’t have any incidence on the ethernet but will somewhat disable your wifi card. (Not exactly but you get the gist of it).
If I’m right it should make all of your problems go away. It might be worth a try. And if it doesn’t work a simple
sudo systemctl enable wpa_supplicantwill reverse it back to the way it was.Ça demeure chiant, même si c’est pas quotidien.
