OT: EC and Kernel module conflict

Hi,

This is OT, because not Fedora, but Kernel specific. It might however 
ring some bells...

I am using an X1 Carbon 9th generation with Fedora 44. It is a known 
problem, that the embedded controller and the kernel acpi modules of 
kernel 7.* have a conflict which results in false rpms on fan 1 (65535) 
and ultimately lets both fans to work with max. rpm, even if the cpu 
deep freezes.

My solution was (after days of tinkering with acpi fan control, 
watchdog, thinkfan, etc., to pull the 6.17.1 Kernel of f43, set it 
default and prevent dnf to do anything with it. Sensors is now 
delivering correct values.

Did anyone else have this problem? Did anyone else succeed to solve it 
by staying with kernel 7.1? An official patch should come in August and 
make it into kernel 7.2 or so, but till than my fans would be twice 
around the world...

Thanks and regards
Tibor
