[arm-allstar] dmesg -T -W

Hi Steve,
This is a commonly reported problem.
Most likely this is due to power supply that doesn't have sufficiently
"stiff" output voltage, as measured directly at the RPi board. I strive to
have 5.25V +/-0.10V, as measured at the RPi power pins on the expansion
bus. Note that excessively high power supply voltage levels (> 5.5V)
could damage RPi board power supply components (particularly some
capacitors on the boards).
I've also seen poor/loose micro-usb power connections cause this problem.
I use custom power supplies, using LM2596S DC-DC converters on all my
"production" systems, with power leads soldered directly to the RPi3
boards and have had excellent results. I've also used various micro-usb
wall warts, with poorer/inconsistent results.
73, David K4FXC
