Also appears related to #1531, but opposite (their fans don't turn off). Is it possible that the kernel upgrade or bootloader upgrade broke the fan dtoverlay and they retain their last known settings? |
Your dtoverlay line is too long. Use Parameters to an overlay can be split over multiple lines by starting the continuations with |
Fair enough, I'll reformat that and see what happens. Just to be clear though, the problem originated before adding anything to config.txt - that was only a troubleshooting step. Previously the fan "just worked" without any manual configuration required |
Since writing that I have reproduced the problem, and am now confused. |
I tried formatting my config.txt like you suggested but same vcdbg log msg output. There's some speculation that a particular commit might have caused the issue |
I'm closing this issue as a duplicate of #1531. |
This isn't a duplicate after all, but it has been diagnosed and fixed in the firmware development repo. Expect a fix to be released in the next few days. |
rpi-update contains the potential fix. Please test and report. |
That seems to have worked! Will report if any strange things happen |
Working again! |
Working here, too, thanks. |
Describe the bug
After standard
apt update && apt upgrade -y
, which upgrades the kernel to 5.10.y and all firmware, the Pi PoE HAT Fan never turns on again despite various different configuration steps. The systems in question are all running stock Raspberry Pi OS 32-bit LiteTo reproduce
From last 2020 lite image:
I also added the following line to config.txt with no success (same result)
Expected behaviour
The Pi boots and the PoE fan starts
Actual behaviour
The Pi boots, but the PoE fan does not start at all.

Additional context
This issue is reproducible on all of my Pi 3B+ units (3x bought from different retailers at different times) and a Pi 4B unit. All 4 devices have the official PoE HAT and were working perfectly until earlier today when I upgraded the kernel. I didn't realize the fans stopped until I upgraded and rebooted the last Pi.
Additionally, all 4 are running stock Raspberry Pi OS 32-bit lite and no modifications were made to the config.txt directly (only through
raspi-config
).The text was updated successfully, but these errors were encountered:
