That much is evident, the question is whether hdaps might also
triggers the same firmware bug.

Whereas hdaps 'position' queries the hardware just once per read, the
'dump' attribute makes 24 back-to-back queries. So if both trigger the
same firmware bug, I expect 'dump' to do it much faster.

Is 'dump' a lot more problematic than other battery status attributes
(e.g., current_now)?
