Wifi interface randomly disappears .

Randomly my wifi interface disappears, then laptop starts behaving abnormally, CPU usage goes to 100%. Dmesg starts giving continuous output like below. I couldn't find anything on google.

An intermittent failure would suggest a hardware problem. Do you still experience the dropout if you run a live session for a while?

See also https://wiki.archlinux.org/index.php/Ne … onnections & https://wiki.archlinux.org/index.php/Ne … ss#iwlwifi

The htop scrot seems to show that the journal is hogging your CPU, have you checked what is being written at that point?

And please use code tags when posting terminal output.

ujj_u · 2020-05-26 07:18:36

Thank you for your reply. Sorry for not using tags. It's my first time posting anything, I will do that in future.

Dropouts are pretty random. It works fine until it doesn't and I have to force shutdown using the power button as even poweroff gets stuck with a black screen. There is no time frame for dropouts.

I will do that in future.

You can actually edit your post and mend it. There's a link in the lower right corner.

Since the ring buffer seems flooded with these errors, please paste the system journal ("sudo journalctl -b") - you can use the pastebin tip in my signature to pipe it directly into a pastebin service (don't copy and paste from a VTE)

Also post the output of "systemctl list-unit-files --state=enabled".

Do you have a parallel windows installation? Do you run additional powersaving tools?

I had installed TLP, I have uninstalled it but didn't change anything, still happens sometimes.
I don't have a parallel window installed. I have Manjaro Linux installed and entry in Grub though.

The output of sudo journalctl -b ( Problem havn't occurred at this time)

You can select older boot journals "… -b -1" is the previous one.
