Title:
Fan speed control not working on Pi 5 under Ubuntu 23.10
Status in linux-raspi package in Ubuntu:
Confirmed
Status in linux-raspi source package in Mantic:
Confirmed
Bug description:
The fan speed control when running Ubuntu 23.10 on a Raspberry Pi 5
does not appear to be working. The fan runs at near maximum speed all
the time and the cur_state in /sys/class/thermal/cooling_device0/ is
stuck at the value of 4 no matter what the CPU temperature. I suspect
it is related to this fault reported on Raspberry Pi OS:
