The reason I'm posting is that I'm unhappy with this workaround and has hoping to dig down and eventually find the real problem :)

The real problem, as well as being about two feet to the right of my 
screen, could be in the trade secret hardware/system management mode 
code on the Broadcom device underlying the Pi.  As already pointed out, 
it is of no real consequence for the intended use of NTP, which is only 
interested in the clock as seen by the software.
