usb-uhci locks up on boot half the time

The NMI oopser for UP only trips in when the cpu is spinning. If the cpu is in a halt state then NMI does not run. But in a halt state you should be able to activate kdb via the pause key. The only time you cannot get kdb via pause is if interrupts are disabled (but then the cpu should be spinning and NMI should kick in) or if the cpu or motherboard is totally wedged.
just a quick followup while i'm working at it. the hardware is totally hung, nothing gets to it, keyboard, serial, or nmi.
being there are a lot of usb functions, does anyone have some suggested breakpoints?
