There was an issue fixed post 2.6.27 where the load balancer didn't work
properly if there was one task per group per cpu. You might try
backporting commit 38736f4 and see if that helps.

Also, caea8a0 fixes up list traversal in load_balance_fair() to use the
_rcu() version. I'm not aware of this causing any problems in practice,
but it might be worth a try.
