White power led

Only recently the behaviour of the white power led changed. The power led starts burning steady but during boot the led starts flashing (heartbeat). I can turn it off in Ubuntu with the trigger command but after a reboot it is flashing again. Also booting in Khadas Resque the led flashes.
I want the steady on behaviour again as it was before the latest (firmware?) update.
How can I change that?
