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.
