Hi, I'm hitting the WARN_ON in $Subject with latest linus: v3.5-8833-g2d534926205d on a 4-node AMD system. As it looks from dmesg, it is happening on node 0, 1 and 2 but not on 3. Probably the pgdat->nr_zones thing but I'll have to add more dbg code to be sure. Config is attached. dmesg: [ 0.000000] Early memory node ranges [ 0.000000] node 0: [mem 0x00010000-0x00087fff] [ 0.000000] node 0: [mem 0x00100000-0xc7ebffff] [ 0.000000] node 0: [mem 0x100000000-0x437ffffff] [ 0.000000] node 1: [mem 0x438000000-0x837ffffff] [ 0.000000] node 2: [mem 0x838000000-0xc37ffffff] [ 0.000000] node 3: [mem 0xc38000000-0x1037ffffff] [ 0.000000] On node 0 totalpages: 4193848 [ 0.000000] DMA zone: 64 pages used for memmap [ 0.000000] DMA zone: 6 pages reserved [ 0.000000] DMA zone: 3890 pages, LIFO batch:0 [ 0.000000] DMA32 zone: 16320 pages used for memmap [ 0.000000] DMA32 zone: 798464 pages, LIFO batch:31 [ 0.000000] Normal zone: 52736 pages used for memmap [ 0.000000] Normal zone: 3322368 pages, LIFO batch:31 [ 0.000000] ------------[ cut here ]------------ [ 0.000000] WARNING: at mm/page_alloc.c:4514 free_area_init_node+0x4f/0x37b() [ 0.000000] Hardware name: Dinar [ 0.000000] Modules linked in: [ 0.000000] Pid: 0, comm: swapper Not tainted 3.5.0+ #9 [ 0.000000] Call Trace: [ 0.000000] [<ffffffff810320bd>] warn_slowpath_common+0x85/0x9d [ 0.000000] [<ffffffff810320ef>] warn_slowpath_null+0x1a/0x1c [ 0.000000] [<ffffffff81470bc0>] free_area_init_node+0x4f/0x37b [ 0.000000] [<ffffffff81af5962>] ? find_min_pfn_for_node+0x57/0x84 [ 0.000000] [<ffffffff81af61a2>] free_area_init_nodes+0x55d/0x5ac [ 0.000000] [<ffffffff81aed7ca>] zone_sizes_init+0x3b/0x3d [ 0.000000] [<ffffffff81aedadc>] paging_init+0x20/0x22 [ 0.000000] [<ffffffff81ae030d>] setup_arch+0x6f3/0x7c2 [ 0.000000] [<ffffffff81add806>] start_kernel+0x8f/0x2eb [ 0.000000] [<ffffffff81add280>] x86_64_start_reservations+0x84/0x89 [ 0.000000] [<ffffffff81add377>] x86_64_start_kernel+0xf2/0xf9 [ 0.000000] ---[ end trace d76bed13a5793ee3 ]--- [ 0.000000] On node 1 totalpages: 4194304 [ 0.000000] Normal zone: 65536 pages used for memmap [ 0.000000] Normal zone: 4128768 pages, LIFO batch:31 [ 0.000000] ------------[ cut here ]------------ [ 0.000000] WARNING: at mm/page_alloc.c:4514 free_area_init_node+0x4f/0x37b() [ 0.000000] Hardware name: Dinar [ 0.000000] Modules linked in: [ 0.000000] Pid: 0, comm: swapper Tainted: G W 3.5.0+ #9 [ 0.000000] Call Trace: [ 0.000000] [<ffffffff810320bd>] warn_slowpath_common+0x85/0x9d [ 0.000000] [<ffffffff810320ef>] warn_slowpath_null+0x1a/0x1c [ 0.000000] [<ffffffff81470bc0>] free_area_init_node+0x4f/0x37b [ 0.000000] [<ffffffff81af5962>] ? find_min_pfn_for_node+0x57/0x84 [ 0.000000] [<ffffffff81af61a2>] free_area_init_nodes+0x55d/0x5ac [ 0.000000] [<ffffffff81aed7ca>] zone_sizes_init+0x3b/0x3d [ 0.000000] [<ffffffff81aedadc>] paging_init+0x20/0x22 [ 0.000000] [<ffffffff81ae030d>] setup_arch+0x6f3/0x7c2 [ 0.000000] [<ffffffff81add806>] start_kernel+0x8f/0x2eb [ 0.000000] [<ffffffff81add280>] x86_64_start_reservations+0x84/0x89 [ 0.000000] [<ffffffff81add377>] x86_64_start_kernel+0xf2/0xf9 [ 0.000000] ---[ end trace d76bed13a5793ee4 ]--- [ 0.000000] On node 2 totalpages: 4194304 [ 0.000000] Normal zone: 65536 pages used for memmap [ 0.000000] Normal zone: 4128768 pages, LIFO batch:31 [ 0.000000] ------------[ cut here ]------------ [ 0.000000] WARNING: at mm/page_alloc.c:4514 free_area_init_node+0x4f/0x37b() [ 0.000000] Hardware name: Dinar [ 0.000000] Modules linked in: [ 0.000000] Pid: 0, comm: swapper Tainted: G W 3.5.0+ #9 [ 0.000000] Call Trace: [ 0.000000] [<ffffffff810320bd>] warn_slowpath_common+0x85/0x9d [ 0.000000] [<ffffffff810320ef>] warn_slowpath_null+0x1a/0x1c [ 0.000000] [<ffffffff81470bc0>] free_area_init_node+0x4f/0x37b [ 0.000000] [<ffffffff81af5962>] ? find_min_pfn_for_node+0x57/0x84 [ 0.000000] [<ffffffff81af61a2>] free_area_init_nodes+0x55d/0x5ac [ 0.000000] [<ffffffff81aed7ca>] zone_sizes_init+0x3b/0x3d [ 0.000000] [<ffffffff81aedadc>] paging_init+0x20/0x22 [ 0.000000] [<ffffffff81ae030d>] setup_arch+0x6f3/0x7c2 [ 0.000000] [<ffffffff81add806>] start_kernel+0x8f/0x2eb [ 0.000000] [<ffffffff81add280>] x86_64_start_reservations+0x84/0x89 [ 0.000000] [<ffffffff81add377>] x86_64_start_kernel+0xf2/0xf9 [ 0.000000] ---[ end trace d76bed13a5793ee5 ]--- [ 0.000000] On node 3 totalpages: 4194304 [ 0.000000] Normal zone: 65536 pages used for memmap [ 0.000000] Normal zone: 4128768 pages, LIFO batch:31 -- Regards/Gruss, Boris.
