You still want to be enabled by default so that normal users can see it and
actually report it.

I don't see how a non-once variant can tell you anything new - it is repeating
one cryptic message to most users so what's the point of parroting it more
than once?

IMO, that message should be beefed up to have more information, dump it once
and encourage users to report it.

Then, whoever gets to debug it, will ask for a reproducer and then do their
own kernel patching to add more info and make the message more useful to them
when debugging the thing.

At least this is how I would do it...
