I noticed a regression report that might or might not be related to hp-wmi; to quote https://bugzilla.kernel.org/show_bug.cgi?id=221569 : """ > Hello, I'm testing 7.1 kernel tree end seeing much louder fan on my laptop even when system is idling. CPU fan is spinning nearly all the time even CPU reported temperatures are low.

""" See the ticket for details and kernel logs, I asked a few questions to hopefully make things a bit easier for you. Maybe you might have an idea what's wrong here; if not, I guess Milan, the reporter (CCed), must bisect this to find the change that causes the problem. Ciao, Thorsten
