If we wanted to debug this we'd likely wanted the actual tid passed into
that function, the caller func:line, and some more meta-information.

If you want to test and debug I can provide you a patch (or temporary put it
into main as I have done for some other WARN* PRs)?

I wonder if this happens (in case you see it again or still have logs with
time stamps) right after wlan0 comes up?

The one thing which makes me wonder is how often it actually happens? Given
it is a WARN_ON_ONCE() we'll only see the first time logged....
