This is because __gpiod_request returned -EBUSY.
Your nvram has following entries:
All of the above GPIOs are reserved by adm6996. It means registering
LEDs failed (because GPIOs 2 and 3 were already in use) and
registering buttons failed (because GPIO 6 was already in use).
Could you find out, which GPIO is connected to your reset button?
Simply export all GPIOs that you can and execute
then press the reset buttong and execute
again. Look for the GPIO that changed it's value.
