Dear Maintainer,
The DELAY=5 seems to be too low for a Lenovo Thinkpad T14s Gen3 AMD. I'm
getting the "no correlation" message when pwmconfig tries to detect the
PWM->fan correlation.
Once I see the message "Testing pwm control hwmon6/pwm1 ..." I do
immediately hear the fan to go from its disengaged maximum of 4900 RPM
to 0 nearly instantly, however it seems it takes a while to get propagated
to /sys/class/hwmon/hwmon6/fan1_input.
In my tests DELAY=10 seems to be at the border, it usually works but
sometimes fails. DELAY=12 or greater seems to be reliable.
You can find a few example outputs (with some extra debug output lines
I had added) for various DELAY values below.
The UEFI System Firmware should be the latest available today (0.1.25
according to fwupdmgr).
Regards, Linus
