Pi4, Ubuntu 19.10 "brcmfmac: brcmf_sdio_htclk: HT Avail request error: -110"

I have a Pi4. I use wired ethernet which works OK and I don't care about or use wifi.
BUT just in case of interest, looks like Ubuntu 19.10 on Pi4 has something wrong with the wifi config, because 'dmesg' gives an unending stream of errors that looks like the below. I wouldn't mind figuring out how to turn off this unending spam to the log file.

EDIT: it looks like sudo nmcli radio wifi off did the trick, as per https://askubuntu.com/questions/597116/ ... mmand-line

Looks like this was addressed a month ago, I guess the Ubuntu dist. just hasn't picked it up yet(?)
