Bug Description
== Comment: #0 - Ping Tian Han <email address hidden> - 2016-12-07 19:14:40 ==
+++ This bug was initially created as a clone of Bug #148750 +++
On roselp4, we got numastat as this:
% sudo numastat
numa_hit 0 0
numa_miss 0 292054
numa_foreign 0 292054
interleave_hit 0 4100
local_node 0 0
other_node 0 0
% uname -a
Linux roselp4 4.8.0-30-generic #32~16.04.1-Ubuntu SMP Fri Dec 2 03:43:52 UTC 2016 ppc64le ppc64le ppc64le GNU/Linux
%
The number of numa_miss and numa_foreign looks wrong, because the manual says that "Each numa_miss has a numa_foreign on another node." and "Each numa_foreign has a numa_miss on another node." But the numbers of node0 are all zeros.
