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?
