Again look like these are disabled channels. At least chanspec 0xd022
is 5G channel 34. You say you get this only once so not every 60
seconds?
I get this everytime i trigger a reconnect to the wifi network, so not
periodically (checked that). Strangely the initial automatic connect
doesn't trigger this errors.
I additionally placed a WARN_ON_ONCE after the error log and enabled the
firmware error log of brcmf_fil_cmd_data(). Maybe this helps.
Here is the output after the first reconnect:
