They're cheap... *very* cheap... They're not the ones Linaro uses in the lab most of the time, but are the ones Linaro has loads of in the "power supply" drawer, and the ones that websites show you as "PandaBoard power supply". Not this one: http://www.digikey.com/product-detail/en/PSAC30U-050/993-1019-ND/2384432?cur=USD This one: http://www.amazon.co.uk/Pandaboard-Board-replacement-supply-adaptor/dp/B0087SU0RU The difference in price tells you a lot... ;) This was my conclusion when my Panda at home, on idle, was locking up. It wasn't turning off every time, some times it'd just lock and have one LED constantly on and the other constantly off, sometimes it'd shutdown completely, and some times the screen would freeze, but it'd still be "running". With many other appliances connected to the same socket (TV, Sky, PS3, printer, etc), the spikes could be causing trouble. The boards now have run overnight at 920MHz without a glitch, though they are understandably 50% slower. I'll see how they behave during today, and if they don't fail, I'll conclude that it was, indeed, the frequency, not the power supply. cheers, --renato
