Maybe it resets because it is trying to draw more current than is available through your configuration.

I checked it now, but the STK500 uses a MAX202 level converter which should be able to output enough current and the power adapter delivers up to 1000mA @ 15V (of course the STK500 turns it down into 5V).

I think I see the dent that you're talking about. It really depends on
how it was created.

It was like that when I got it.

That's not good. If you have a Wifi chip, then the resetting is
normal. If you don't, then I would be inclined to return the gumstix
for RMA.

I don't have a WiFi chip so I guess I'll have to get an RMA and return it. I ordered another Verdex yesterday to speed things up with my project (might come in handy anyway), so I guess I'll wait for it and check if it behaves the same way. If not, there's no doubt it's defect. 

Thanks for the response guys :)
