Please do not top post. Answer comes after questions, not before...

You should have something similar.

I have no LEDs on this box, but you should should see entries in

/sys/class/leds

What you probably see in the kernel logs is lots of warnings from gpio
about deferred, but then they get repeated later and are successful.
