i've seen this ldi_get_size() failure before and it usually occurs on
drivers that don't implement their prop_op(9E) entry point correctly
or that don't implement the dynamic [Nn]blocks/[Ss]size property correctly.
what does your layered driver do in it's prop_op(9E) entry point?
also, what driver is your layered driver layered over?
