When booting a 32-bit x86 kernel on a NUMA machine, node data cannot be allocated from local node if the account of memory for node 0 covers the low memory space entirely: [ 0.000000] Initmem setup node 0 [mem 0x00000000-0x83fffffff] [ 0.000000] NODE_DATA [mem 0x367ed000-0x367edfff] [ 0.000000] Initmem setup node 1 [mem 0x840000000-0xfffffffff] [ 0.000000] Cannot find 4096 bytes in node 1 [ 0.000000] 64664MB HIGHMEM available. [ 0.000000] 871MB LOWMEM available. To fix this issue, node data is allowed to be allocated from other nodes if the memory of local node is still not mapped. The expected result looks like this: [ 0.000000] Initmem setup node 0 [mem 0x00000000-0x83fffffff] [ 0.000000] NODE_DATA [mem 0x367ed000-0x367edfff] [ 0.000000] Initmem setup node 1 [mem 0x840000000-0xfffffffff] [ 0.000000] NODE_DATA [mem 0x367ec000-0x367ecfff] [ 0.000000] NODE_DATA(1) on node 0 [ 0.000000] 64664MB HIGHMEM available. [ 0.000000] 871MB LOWMEM available.
