Thanks for the explanation.

Could we add a kernel parameter to hide this? It could land in core-for-CI, and
we could even try to upstream it.

Generating this warning in every run on every machine just fills the database,
and adds noise to results which confuse people (dmesg-warn is not an acceptable
status).
