I have installed a fresh new debian on my Netgear Ready RN314 and the lcd panel keep lighting so i decided to rewrite the kernel module to control lcd, buttons and leds. Before you try it, i STRONGLY encourage you to unmount your raid. It work well on my nas, but well we never know.
Please note that i have nothing to do with Netgear.
Check your nas
