Well, it's a stock N900, not a development board so I don't have a serial; only the screen and the led in the left corner below the screen. By "device stops" I mean that the screen and the led (which was previously on) get dark and stay as is. I also suspected a HW watchdog but 25 seconds did not sound like it. I built a kernel without HW watchdog: same result. Any idea regarding how I could debug that? Cheers, a+
