 But, it does finish booting the kernel, so it seems reasonable to
 conclude that the problem is usb-related. (this is not exactly
 surprising)
 
 I can't think of anything else to try but doing a binary search
 disabling specific usb devices until you find the one that causes it
 to choke. But I'm not the usb expert, so maybe someone else will have
 a better idea...
