In the past few days, I have observed that: - if my wireless connection is set on the 5 GHz band - when the router switches the channel - a notification that the connection is lost is displayed - within seconds, a new connection is made on the 2.4 GHz band (I have a connection profile with lower priority)
I have: - NO MORE freeze because the log files are taking all the disk space - NO MORE freeze with no possibility to disconnect Network Manager Actually this behaviour on channel switch has been consistent during the last few days and is now what I had with Ubuntu 19.10 and older releases. I don't know what updates made things change but the current situation is fine for me. Kernel is 5.4.0-48-generic x86_64 fully updated and using wpa_supplicant ** Attachment added: "syslog on channel switch" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1881214/+attachment/5419676/+files/syslog%20part -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1881214 Title: Intel Wireless 8260 [8086:24f3] Subsystem [8086:1010] on channel switch, iwlwifi Microcode SW Error: FW error in SYNC CMD CHANNEL_SWITCH_TIME_EVENT_CMD Status in linux package in Ubuntu: Confirmed Bug description: 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. edit: and when the event starts.
