There is about 1GB of memory on node 0, which is about half of the partition's memory, and it is even in a contiguous chunk, but it doesn't start at pfn 0: early_node_map[3] active PFN ranges 1: 0 -> 32768 0: 32768 -> 278528 1: 278528 -> 524288 So it's not that node 0 doesn't have any pages. Any other clues?
