[buug] Hardware heartburn

Just curious Bill, but is anything plugged into the
USB port?  If you plugin something else, does that
work?  Is there another USB port you can plug into
instead (ie is it the device, the cable, or the USB
port ? )  

If nothing is plugged in to the USB port, and you
don't plan on using the USB port, you could disable
all the USB/PCI stuff to allow the kernel to boot.
