I believe most of the bad things he was accused of turned out to be FUD, Kompromat and defamation.

Ass-to-ass.

I think this is unlikely because it’s only this specific device that crashes, and the others are fine?

No, good old SSID+passphrase. But this PC is connected via ethernet (although the mobo does have a wifi chip, that I don’t use).

Nope, I don’t know the first thing about these tools, but now I’m kind of impatient and hope that the next freeze happens soon so I can try. :-)

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…

I like my debian vanilla but thanks for the suggestion. The other network card would be interesting to try out. I don’t really suspect the network card, since I have no idea whether the network block is a consequence or a cause here.

Nope. May I ask what would be the connection with my issues?

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.

Oh this would explain why it kills the connectivity of all ethernet-connected devices. The ethernet interface is the one on the mobo. Drivers are included by the linux kernel AFAIK. The problem persisted across 2 debian versions so I am not sure re-installing drivers would do anything here. But thanks for the plausible explanation about the network issue!

This has been happening for 2 years, with the previous debian version too, so I doubt this would do anything?

It happened yesterday, and here are the latest log lines before the freeze:
