If we free the firmware area we are guaranteed to crash. That is ppc64 bug. firmware should not be in the reserved region. Any random kernel like thing can be put in to that region at any valid address and the fact that shrinking the region frees your firmware means that using that region could also stomp your firmware (which I assume would be a bad thing). So please fix the ppc64 reservation. Eric
