Thank you very much for this code and information. I would say the
blinking of mine was the same (slow) speed in all cases (but I'm not
100% sure) - so maybe no kernel panic. But my battery was definitely not
empty... This does not happen often anyway (maybe once in 2 wweks) and 
is not a big deal for me if it is working again after some minutes.
