Using this option can access some devices in such a
manner as to leave them in an unstable or unuseable state, and
can prevent those devices from being properly matched and/or
attached. It can also lock up the entire i2c bus and even
prevent a machine from completing the boot process. Don't
use this option unless you know what you're doing and can
accept all sorts of unforseen consequences.
