Dear Maintainer,
If pwmconfig detects "no correlation" between the configured pwm1
speed and the resulting output value in fan1_input in my case (due to
the too low DELAY value, as reported in another ticket) and if I then
choose to perform the auto-detection for the "minimum PWM value" then
this hangs indefinitly on:
```
function TestMinStop()
{
[...]
fanspeed=$(cat $faninput)
```
Because $faninput is an empty string. See more detailed output below.
Regards, Linus

$ sudo pwmconfig
# pwmconfig version 3.6.0
This program will search your sensors for pulse width modulation (pwm)
controls, and test each one to see if it controls a fan on
your motherboard. Note that many motherboards do not have pwm
circuitry installed, even if your sensor chip supports pwm.
We will attempt to briefly stop each fan using the pwm controls.
The program will attempt to restore each fan to full speed
after testing. However, it is ** very important ** that you
physically verify that the fans have been to full speed
after the program has completed.
Found the following devices:
hwmon0 is acpitz
hwmon1 is BAT0
hwmon2 is nvme
hwmon3 is amdgpu
hwmon4 is AC
hwmon5 is k10temp
hwmon6 is thinkpad
hwmon7 is ath11k_hwmon
Found the following PWM controls:
hwmon6/pwm1 current value: 0
Giving the fans some time to reach full speed...
Found the following fan sensors:
hwmon6/fan1_input current speed: 4926 RPM
Warning!!! This program will stop your fans, one at a time,
for approximately 5 seconds each!!!
This may cause your processor temperature to rise!!!
If you do not want to do this hit control-C now!!!

no correlation
No correlations were detected.
There is either no fan connected to the output of hwmon6/pwm1,
or the connected fan has no rpm-signal connected to one of
the tested fan sensors. (Note: not all motherboards have
the pwm outputs connected to the fan connectors,
check out the hardware database on http://www.almico.com/forumindex.php)
Did you see/hear a fan stopping during the above test (n)? y
Testing is complete.
Please verify that all fans have returned to their normal speed.
The fancontrol script can automatically respond to temperature changes
of your system by changing fanspeeds.
Do you want to set up its configuration file now (y)? y
What should be the path to your fancontrol config file (/etc/fancontrol)?

Enter the minimum PWM value (0-255)

Now we decrease the PWM value to figure out the lowest usable value.
We will use a slightly greater value as the minimum speed.
