Created attachment 300133 [details] dmesg-5.4.167.txt Hi, I jumped from 5.4.143 to 5.4.167 but the connection to wifi was so unstable I had to reboot to use the old kernel. I never used git bisect and am not sure I have that much time to play with that. However, let me say that I lost about 5x connection to AP. Sooner or later after each situation I disconnected from the AP using nm-applet and re-connected. That has helped for a short while, liek a few minutes, then I again lost network connection. Maybe you can find the event in the dmesg output. Once, for some reason, there is also a stacktrace from the kernel. Why just onceinstead of about 5 times I have no idea. I could provide the same kernel messages supplemented with daemon messages from syslog. Hope this helps to some extent,
Just wondering: is this issue still present in the latest 5.4 kernel? If it is it would be a great help to bisect this
Hi, indeed I was already thinking to report back. I recompile dteh kernel with extra debug info but since then I am using this 5.4.167 kernel which I believed suffered from a regression. I have to admit it must have been a temporary wifi issue not related to my Linux device. if I could speculate, maybe it was related to speed negotiation or some re-keying. These messages were logged time to time. [674957.141940] userif-2: sent link down event. [674957.141945] userif-2: sent link up event. [676532.057814] userif-2: sent link down event.
