Public bug reported:
To report this bug, I have downgraded to 3.20210216.0ubuntu0.21.04.1.
After upgrading to latest security update of intel-microcode, my wifi
reception is cut every second and restart with:
juin 10 09:32:55 casanier wpa_supplicant[2158]: wlp3s0:
CTRL-EVENT-REGDOM-CHANGE init=DRIVER type=WORLD

detected. Restarting 0x2000000.
juin 10 09:32:56 casanier kernel: iwlwifi 0000:03:00.0: Start IWL Error Log
Dump:
juin 10 09:32:56 casanier kernel: iwlwifi 0000:03:00.0: Status: 0x00000040,
count: 6
The network connection is thus unusable. Downgrading will stop showing the
previous error in the journal.
I have attached the whole log corresponding to this error. It’s
restarting every second approximately.
