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). commit 50f2d7f682f9c0ed58191d0982fe77888d59d162 Author: Nikanth Karthikesan <knikanth@suse.de> Date: Thu Sep 30 17:34:10 2010 +0530 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
Yinghai posted a patch for this: http://lkml.org/lkml/2010/11/13/176 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. *** Bug 22702 has been marked as a duplicate of this bug. *** The Patch in Comment #3 has been tested by Wu Fengguang. Patch: http://lkml.org/lkml/2010/11/13/176 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.
