One system doesn't have RAM for node0 installed. SRAT: PXM 0 -> APIC 0 -> Node 0 SRAT: PXM 0 -> APIC 1 -> Node 0 SRAT: PXM 1 -> APIC 2 -> Node 1 SRAT: PXM 1 -> APIC 3 -> Node 1 SRAT: Node 1 PXM 1 0-a0000 SRAT: Node 1 PXM 1 0-dd000000 SRAT: Node 1 PXM 1 0-123000000 ACPI: SLIT: nodes = 2 10 13 13 10 mapped APIC to ffffffffff5fb000 ( fee00000) Bootmem setup node 1 0000000000000000-0000000123000000 NODE_DATA [000000000000e000 - 0000000000014fff] bootmap [0000000000015000 - 00000000000395ff] pages 25 Could not find start_pfn for node 0 Pid: 0, comm: swapper Not tainted 2.6.24-smp-g5a514e21-dirty #14 Call Trace: [<ffffffff80bab498>] free_area_init_node+0x22/0x381 [<ffffffff8045ffc5>] generic_swap+0x0/0x17 [<ffffffff80bab0cc>] find_zone_movable_pfns_for_nodes+0x54/0x271 [<ffffffff80baba5f>] free_area_init_nodes+0x239/0x287 [<ffffffff80ba6311>] paging_init+0x46/0x4c [<ffffffff80b9dda5>] setup_arch+0x3c3/0x44e [<ffffffff80b978be>] start_kernel+0x6f/0x2c7 [<ffffffff80b971cc>] _sinittext+0x1cc/0x1d3 This happens because node 0 is not online, but the node state in mm/page_alloc.c has node 0 set. nodemask_t node_states[NR_NODE_STATES] __read_mostly = { [N_POSSIBLE] = NODE_MASK_ALL, [N_ONLINE] = { { [0] = 1UL } }, So we need to clear node_online_map before initializing the memory.
