I think I can tell more about the circumstances: 1* My computer is connected by Wifi to the modem / router on the 5 GHz band, (let's say) canal 100. 2* After a certain amount of time, the router switches *itself* the canal to 36 or 52. This amount of time is vary variable and independent of what I'm doing on my computer, hence the difficulty to describe the circumstances. 3* There is no indication that the connection is lost. There is no attempt to connect on the 2.4 GHz band, even though I have a connection profile. Then, syslog and kern.log start to grow endlessly, see bug description.
With previous versions of Ubuntu: 1* and 2* Same. 3* The connection is lost but very shortly after that the Wifi card connects on the 2.4 GHz band. ** Description changed: Ubuntu Mate 20.04, with all supplied kernels up to 5.4.0.33 I occasionally see a message on my screen that disk space is low. 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. + 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.
