I have assembled my desktop PC about 2 years ago. Itâs fairly beefy (AMD Ryzen 9 3950X 16-Core Processor, 128Go RAM, nVidia RTX 3080 Ti). Itâs 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 âfreeze my networkâ too, ie, other (ethernet) devices on my local network have no connectivity anymore. Theyâre 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?
Have you been updating or reinstalling ?
Parce que si câest update sur update ça pourrait venir de lĂ . Dans ce cas rĂ©installe peut etre ?
Updating. Iâm 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? Wouldnât resetting the config files be more efficient btw?
EDIT: Ce nâest pas update sur update, y a juste eu bullseye (dâabord testing, puis stable), puis rĂ©cemment je suis passĂ© Ă bookworm. Mais le soucis est lĂ depuis le dĂ©but. Il est pas trop chiant parce que câest rare, mais quand mĂȘme ça mâenquiquine.
Thing is, I really havenât used debian based distros for the better part of the last two years so Iâm 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 donât have a backup .deb. Iâm 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 donât use it at all there is a simple trick : sudo systemctl disable wpa_supplicant then reboot.
It wonât have any incidence on the ethernet but will somewhat disable your wifi card. (Not exactly but you get the gist of it).
If Iâm right it should make all of your problems go away. It might be worth a try. And if it doesnât work a simple sudo systemctl enable wpa_supplicant will reverse it back to the way it was.
Ăa demeure chiant, mĂȘme si câest pas quotidien.
