Same issue here. Ubuntu 20.04 fully updated running on a Dell Latitude
5590. Started after VPN connection over wifi. It works ok sometime and
then VPN and network stopped working in this case. Changing to cabled
connection just in case meanwhile the issue gets solved.

Pasting repeated log just in case (few lines):

Same issue here (logs filling up the disk because of wifi-related

2020-07-06 Thread nyarla33
The behaviour on channel switch on the 5 GHz band seems somehow erratic as what 
happens can be either:
1 - what I described in post #23
2 - syslog and kern.log grow endlessly, as seen before
3 - the wifi card disconnects and manages to reconnect itself as seen in 
included log file "syslog reconnection completed"

2020-07-02 Thread nyarla33
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.

2020-06-09 Thread nyarla33
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.

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.
