Backlight on means the SQWE flag (square wave enable bit) is 1, and in this case it hangs in most cases. Could this be a general problem? I think it could also lead to hang ups if power_off is called in powermgmt.c because of the auto-shutoff feature and the backlight is on! (It only hasn't happened in the past because the user has usually (backlight timeout) < (shutoff time) ). Suggestion: power_off should turn the backlight off by clearing the sqwe bit in the rtc.
