[Kernel-packages] [Bug 1881214] Re: 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
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.

This bug is not present with other distro's I use, that is Arch. This indicates that it can be distribution centric. Ubuntu has the bug, Arch does not. A workaround is if your system has this Intel device use another distro.

Maybe I was too happy too soon. Today, using iwd, when the channel on the 5 GHz network switched, the connection was lost but there was no notification and it was impossible to connect to another ssid. The log files didn't grow endlessly though. -- 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.

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.

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.

By installing an OLDER mainline kernel 5.3.18-050318-generic x86_64, the behaviour has reverted to what I had before Ubuntu 20.04, meaning: if the router switches the canal for the 5 Ghz band, connection is lost and then a new connection is set on the 2.4 Ghz band. Interestingly, what can be seen in attachments in message #4 and #5 is happening too but is not reproduced endlessly, just a few attempts. ** Attachment added: "syslog (older kernel)" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1881214/+attachment/5382011/+files/syslog%20%28older%20kernel%29 -- 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.
