Hmm.. I couldn't reproduce on my system: # node0 meminfo : total = 33505624 kB, free = 25213528 kB # node0 cpu list : 0-11 # pmu mappings: cpu = 4, software = 1, uncore_pcu = 13, tracepoint = 2, uncore_imc_0 = 15, uncore_imc_1 = 16, uncore_imc_2 = 17, uncore_imc_3 = 18, uncore_qpi_0 = 19, u = 20, uncore_cbox_0 = 7, uncore_cbox_1 = 8, uncore_cbox_2 = 9, uncore_cbox_3 = 10, uncore_cbox_4 = 11, un = 12, uncore_ha = 14, uncore_r2pcie = 21, uncore_r3qpi_0 = 22, uncore_r3qpi_1 = 23, breakpoint = 5, uncore_ubox = 6 I don't have a NUMA machine.
