Yes... that makes good sense Dwight.  Some marginal bits in the
initialization code or some such.   Scoping the bus does seem to indicate
that it is more software related...  ie, I am not seeing weird levels
or signs that outputs are driving outputs or unable to drive full swing.
It just seems to run a little and then stop when it is not frozen.
