Hi everybody, This is my first post over here, so apologies if this is not in the right format. I discovered the following issue with the fans of my Helios4 Armada388 system yesterday, after upgrading to the latest version of OMV based on Armbian 22.08.4 Bullseye with Linux 5.15.72-mvebu: The fans were spinning very fast and thus making a lot of noise. This was a new issue. I looked at the fancontrol utility and noticed that the config was broken on Armbian 22.08.4 Bullseye with Linux 5.15.72-mvebu From the logfiles: Oct 12 07:23:36 helios4 kernel: [ 14.629414] hwmon hwmon2: temp1_input not attached to any thermal zone Oct 12 07:23:36 helios4 kernel: [ 14.629422] lm75 0-004c: hwmon2: sensor 'lm75' Oct 12 07:23:36 helios4 kernel: [ 15.520811] pwm-fan j17-pwm: error -EBUSY: Could not get PWM Oct 12 07:23:36 helios4 kernel: [ 15.520824] pwm-fan: probe of j17-pwm failed with error -16 Oct 12 07:23:37 helios4 fancontrol[1313]: Settings for /dev/fan-j10/pwm1: Oct 12 07:23:37 helios4 fancontrol[1313]: Depends on /dev/thermal-cpu/temp1_input Oct 12 07:23:37 helios4 fancontrol[1313]: Controls Oct 12 07:23:37 helios4 fancontrol[1313]: MINTEMP=40 Oct 12 07:23:37 helios4 fancontrol[1313]: MAXTEMP=80 Oct 12 07:23:37 helios4 fancontrol[1313]: MINSTART=20 Oct 12 07:23:37 helios4 fancontrol[1313]: MINSTOP=29 Oct 12 07:23:37 helios4 fancontrol[1313]: MINPWM=0 Oct 12 07:23:37 helios4 fancontrol[1313]: MAXPWM=255 Oct 12 07:23:37 helios4 fancontrol[1313]: AVERAGE=1 Oct 12 07:23:37 helios4 kernel: [ 27.722907] EXT4-fs (dm-0): mounted filesystem with ordered data mode.

Either some required kernel Oct 12 07:23:38 helios4 fancontrol[1720]: modules haven't been loaded, or your configuration file is outdated. Oct 12 07:23:38 helios4 fancontrol[1720]: In the latter case, you should run pwmconfig again.

Oct 12 07:23:38 helios4 systemd[1]: fancontrol.service: Consumed 1.012s CPU time. On the website https://wiki.kobol.io/helios4/pwm/ I read the following: "Patch requirement Currently Linux gpio-mvebu driver does not allow more than 1 PWM under the same gpio bank. Helios4 uses 2 PWM under same bank therefore this patch needs to be applied to kernel source to remove the restriction." I assumed there was something wrong with the kernel. Downgrading to kernel helios4 5.15.69-mvebu #22.08.2 solved the issue of fancontrol not working. So I assume the required patch, that was always there IMO, has been removed from the latest kernel. Any thoughts on this issue?
