It isn't the voltage so much as it ishow much current the power
adapter can deliver.

The gumstix power adapters are rated for 1A (1000mA). I suspect that
your power adapter is only rated for a much lower number, like 200mA.

Many voltage regulators have thermal shutdown modes so that if you try
to draw too much they shutoff, and this is what's resetting the
gumstix.As sonn as the gumstix is off the current draw drops and the
power adapter turns back on.
