Hi! I look out for reported regression in bugzilla.kernel.org and
normally ignore everything else. But I noticed a newly submitted report
that sounded somewhat bad, that's why I decided to write this mail to
ensure the right people are at least aware of it.

> Windows has software which allows fan to reach high speed with
