I start Prime and it runs OK for a while. Then, at some point the system hard restarts (as if reset has been pressed) and freezes during post. The exact operation it freezes on is "Initializing USB controllers". It doesn't matter if there are no USB devices attached at all, it just freezes there during post. Even resetting CMOS doesn't help reliably.

Sometimes it will post again (not easy), and then repeat until next time. This is the most annoying problem I have ever encountered.
Oh well it turns out the techs at ASUS just reset the bios of my screwed up board and shipped it back to me when I RMA'd it after having the same damn problem. Talked to level 2 support today on the phone and the board is going back for a non-ignorant service. So the above is almost certainly a hardware fault of some sort.
