The logical ring code was updating the software ring 'head' value by reading the hardware 'HEAD' register. In LRC mode, this is not valid as the hardware is not necessarily executing the same context that is being processed by the software. Thus reading the h/w HEAD could put an unrelated (undefined, effectively random) value into the s/w 'head' -- A Bad Thing for the free space calculations.
