Package: src:linux Version: 4.19.152-1 Severity: normal Dear Maintainer,
I am running debian buster AMD64 on Xiaomi air 12 laptop (intel cpu and wifi) with KDE and network-manager. Since 21th of October I am experiencing frequent (0-4 times an hour) drops of the wifi connection to my Router (Fritzbox 7530) or the additional access point (TP-Link AC750 Archer C2). In these cases the connection is lost and I am prompted for the correct password. However, the password did not change and is still correct. Canceling the dialog and clicking connect in NM recreates the connection.

Therefore I checked what has changed and found out that a new kernel (linux-image-4.19.0-12-amd64) was installed the day before. I then tried the buster backport kernel (linux-image-5.8.0-0.bpo.2-amd64) and also the previous kernel (linux-image-4.19.0-11-amd64). The problems directly disappeared for both. Booting again linux-image-4.19.0-12-amd64 the wifi dropped again. Therefore I am pretty sure that the problems are caused by linux-image-4.19.0-12-amd64. I experienced the same problem in another loacation with different router (also Frizbox 7530) and different laptop (Acer C740 with debian buster AMD64 running KDE and network-manager).
