Comment 1 Myron Stowe 2010-11-11 00:04:41 UTC
Bisecting the kernel gave the following results.  Note that I only had half the logical CPUs turned on (64 of 128) on this platform (hp dl980g7).

    x86, numa: Assign CPUs to nodes in round-robin manner on fake NUMA
    
    commit d9c2d5ac6af87b4491bff107113aaf16f6c2b2d9 "x86, numa: Use near(er)
    online node instead of roundrobin for NUMA" changed NUMA initialization on
    Intel to choose the nearest online node or first node.  Fake NUMA would be
    better of with round-robin initialization, instead of the all CPUS on
    first node.  Change the choice of first node, back to round-robin.
    
    For testing NUMA kernel behaviour without cpusets and NUMA aware
    applications, it would be better to have cpus in different nodes, rather
    than all in a single node.  With cpusets migration of tasks scenarios
    cannot not be tested.
    
    I guess having it round-robin shouldn't affect the use cases for all cpus
    on the first node.
    
    The code comments in arch/x86/mm/numa_64.c:759 indicate that this used to
    be the case, which was changed by commit d9c2d5ac6.  It changed from
    roundrobin to nearer or first node.  And I couldn't find any reason for
    this change in its changelog.

[Possible fix] Fallback to first node, if the node is not online
Comment 3 Dan Carpenter 2010-11-14 18:27:56 UTC
Yinghai posted a patch for this:  http://lkml.org/lkml/2010/11/13/176
Comment 4 Myron Stowe 2010-11-14 18:33:53 UTC
There are two email threads concerning this (thanks Yinghai for noticing this):
  http://lkml.org/lkml/2010/11/4/6
and
  http://lkml.org/lkml/2010/11/11/77


I tested the possible fix in Comment #2 and still got the same divide error.

The Patch in Comment #3 has been tested by Wu Fengguang. 
Patch: http://lkml.org/lkml/2010/11/13/176
Comment 7 Myron Stowe 2010-11-20 00:21:09 UTC
The patch in Comment #3 was also successful when tested on the HP dl980g7 however I strongly feel that the patch's header and description need rewritten.
