Just to be sure: So the warning the only problem? I.e. does the hardware
act as AP just fine otherwise?

Can you please test a newer kernel from forky (or trixie backports) and
report back about the behaviour there?
Depending on the issue being reproducible with this newer kernel we have
to report upstream or determine the fixing commit and ask for
backporting to stable.

Best regards
Uwe
