Well it at least proves this is happening from firmware/hardware and not
(obviously) from your own doing in software.  I think it still needs further
characterization.

Just as a guess; could this be related to lap mode?  There is a lap mode value
stored in `dytc_lapmode`.  Can you add that to your output?


@Mark maybe you can help explain this?

If nothing else I think it would be good to extend some dev_info messaging when
this is happening.
