I don't think this is your fault. My initial patch for this problem had a loop 
in the mount root code, trying to mount the root device several times. Now 
several other people did not agree about that, and made the USB enumeration 
synchronous instead. That does not always work, because USB devices do not 
always show up immediately when the power is turned on. I would strongly 
suggest to add a flag to the mount root code in sys/kern/, allowing the mount 
root code to automatically retry the medium. It is also important that the 
mountroot code calls pause() and do not spin in a while loop.
