With the recent updates, including: kernel 5.4.0-40-generic x86_64 and (I suspect) wpasupplicant 2:2.9-1ubuntu4.1 The behaviour has changed: on channel switch the log files no longer grow endlessly but there is still no attempt to reconnect to another SSID nor notification that the connection is lost. Instead the system basically freezes and it's impossible to manually disconnect the wifi.

I try rebooting since my computer is unresponsive. Normal reboot does not work, sudo reboot does not work. I have to power off the machine using power button. Machine boots but hangs because its trying to repair journal info. I can't see what causes that since I was not using my computer at the time. edit: see comment #14 So with a live session, I can see that syslog and kern.log files have grown to several GB until the drive is full. When using an upstream kernel 5.4.43-050443-generic x86_64, I haven't had any problem so far. edit: not true actually, this happened again using this upstream kernel. Never had this issue with previous Ubuntu versions with the very same hardware configuration, since 16.04. Included: partial syslog and kern.log with the same message repeated over and over. edit: and when the event starts.
