>Description:
	Every other reboot, the kernel panics before even mounting root when 
	probing USB.  If I don't have my USB hard drive attached, all is okay 
	until I plug it in. (sometimes crashes, sometimes not)  A hand
	transcribed trace of the panic:

	panic()
	ohci_add_done() + 0x66
	ohci_intr1
	ohci_intr
	Xintr5
	-- interrupt --
	idle
	bpendtsleep
	usb_delay_ms
	usbd_new_device
	uhub_explore
	usb_discover
	usb_event_thread

	Perhaps some sort of delay timing/ race condition issue?

	Here's my dmesg:
