I have two BBBs' both running with an ArchLinuxARM image flashed onto the eMMC chip. Both boards are updated and as far as I can remeber have the same packages installed. Now there is a difference in their behavior regarding the power button. One board does a soft poweroff when pushing the power button, the other does not.
I found this guide but even with acpid no poweroff is done by the board. Are there any other recommendations on how to perform a soft poweroff?
Or could this behavior even be a result of some kind of hardware issue? How could I track down a bug like that?
Thx in advance..
EDIT: I compared the two BBBs' again and saw that the one doing a soft poweroff still was on kernel 3.14. After the update to kernel 4.1 the soft poweroff functionality was gone. So how can I restore that behavior?
