Could very well be a hardware flaw in the controller, one that isn't
worked around in software by DF (yet).
Basic idea is that DF sends a series of commands that are valid but
throw the controller into a loop. Communications eventually time out,
so DF resets the controller.
Sadly, these kind of hardware bugs seem to be on the increase.
