Unfortunately a ppc64 kernel requires a chunk of RMO memory. We would need the ability to specify multiple crashkernel regions - about 32MB in the RMO and the rest can be anywhere. That sounds pretty fragile for a user to configure successfully on the cmdline. Thats why the ppc64 crashkernel region begins mid way through the RMO region. It means both kernels get a chunk of RMO and we only have to deal with one crashkernel reservation in all the tools and documentation. Anton
