Oh that's a 32bit kernel. I don't think the 32bit NUMA has ever worked
anywhere but some Summit systems (at least every time I tried it it blew up 
on me and nobody seems to use it regularly). Maybe it would be finally time to mark it 
CONFIG_BROKEN though or just remove it (even by design it doesn't work very well) 

If you want NUMA use 64bit.
