Public bug reported:
I'm using a built-in RTL8822BE WiFi adapter on a Ryzen 7 system. When I
create a hotspot by opening the GNOME settings app, opening the WiFi
settings page and selecting "Turn on hotspot..." from the drop-down
menu, everything works fine. If I then open nm-connection-editor and
edit the connection to select band A (5GHz), the hotspot fails to start.
If I then open the connection editor again and switch back to automatic
band selection, the hotspot works again.
When it fails, this appears in syslog:

I'm guessing that NetworkManager is getting the way it drives
wpa_supplicant wrong when the 5GHz band is selected, but it's only a
guess.
