Where does the boot problem occurres, in what phase (if you hang on the
serial port)? When I started using the TS72.., the board sometimes hang
or rebooted, this was due to bad power supply. The board might do some
peaks, especially when the ethernet interface is enabled. Just with the
volt meter, I did not manage to measure the voltage drop, however a
better power supply saved me out of the situation.
