Both you and Eric are having issues with Opteron 6300 series CPUs.

I can't help but think the fact that each package in a socket has 2 NUMA nodes 
is the cause of your pain. So whilst Slurm says it's treating each NUMA node 
as a socket I wonder if at some point it's getting confused whether the number 
of sockets is really 2 or 4?

No, that's definitely wrong.

What does this say?

grep -R rocks7 /etc/slurm

All the best,
