I don't know if it's the controller, the disk or the ehci driver. However, man ehci(4) states that "The driver is not finished and is quite buggy." This seems to be true. I get all sorts of trouble ranging from hangs during boot to system crashes. I am reverting back to USB1 although its terribly slow.
