Yup - something is different. I never saw the lightning bolt before, but
monitoring the voltage regulator during startup, I am definitely getting
a momentary drop below 4.95 volts. My ps may be suffering from
inadequate filtering (need more capacitance), causing the LT1803
regulator to dip below spec.  I'll be be taking a closer look and
modifying the supply as needed. The dip happens consistently on boot -
so for some reason, the Pi is requiring more current during startup than
before. During normal operation, it is fine.

Thanks

Whit
