Apparently, somehow the channel switch is fatal: wlp2s0: driver channel switch failed, disconnecting
** 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. 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. + Included: partial syslog and kern.log with the same message repeated over and over. + edit: and when the event starts. ** Summary changed: - syslog and kern.log grow endlessly - related to Intel wifi? + syslog and kern.log grow endlessly - related to channel switch, Intel wifi? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1881214 Title: syslog and kern.log grow endlessly - related to channel switch, Intel wifi?
