The board worked fine with some random set up rsalveti provided me with, but that didn't seem to have USB support so maybe it didn't probe for USB devices at startup. The fact that the reset button doesn't work -- you have to yank the power out -- suggests that maybe it is power related. But just a guess.

I have seen boards work fine until the voltage dips as a result of USB devices getting turned on. 2. This reminds me of how the mx51 kernel was behaving when u-boot was enabling the watchdog timer but the kernel was not disabling or updating it. I don't notice if it's related, but I've just noticed that if I press reset during boot (but before the hang), the board still powers down a few seconds later (before the next attempt at booting gets going). Resetting on line 19 of http://pastebin.ubuntu.com/560790/ was OK, whereas resetting on line 40 was not.
