Hi Ian,

I only switched the kernel. Anything else remains the same. I will
check for the "modules effect" you described and I am prettu sure,
that this will in my case, also!

I will report later, if a will have some results...

Cheers!

Something similar happened to me too with a recent kernel upgrade but in
the 5.4's.

The reason was that my kernel config changed to build the default CPU
powersave driver as a module, and apparently that is a poor idea, it
needs to be built in.  When I rebuilt the kernel with the driver built
in, the fan went back to normal.

In your case: are both scenarios on the same hardware, since as we all
know you're just switching?
