 OK, so it's probably not caused by uhci.c rev 1.223. You could try reverting
 it to 1.222 to see if it changes anything, but I don't think so.

 there's still more than one minute before getting the first message (and
 probably more than that because syslog doesn't start right after init).
 So I guess something is corrupting uhci's memory.
 Could you see if not using ath (maybe disabling it with boot -c) would
 avoid the issue ?
