Without this return the hook function will execute only once. And, regions with type GRUB_MEMORY_RESERVED should be skipped. So the hook function body should look like this: if (type != GRUB_MEMORY_RESERVED) { total_mem_bytes += size; } return GRUB_ERR_NONE; After this change the result looks fine.
