Yeah, I also understood the problem to be the SRAT, not the DSDT... Of course you could reserve a single large part of the address range in "-numa mem", and then add one or more DIMMs covering only part of the address range. Perhaps "populated" could be a size instead of a boolean, to do something like what Igor suggested. Paolo
