I just bought a Raspberry Pi 3 Model B with NOOBS microSD Card. I only connected the USB cable for power and the HDMI cable, it keeps rebooting with these errors, like it is stuck in a loop.
/init: line 27: can't create /sys/class/leds/led0/trigger: nonexistent directory

If I plug a "microsoft all in one media keyboard" it goes in kernel panic.
