Oh shit, what did I get into!? I only wanted to do a quick fix and get
back to the real, manly bugs!

Ok, I'll do all that you suggested and send you the results.

Btw, qemu is so cool in generating the craziest topologies and much
easier than me actually going and looking for such a real big system:

kvm -smp 64 \
-numa node,nodeid=0,cpus=0-7 \
-numa node,nodeid=1,cpus=8-15 \
-numa node,nodeid=2,cpus=16-23 \
-numa node,nodeid=3,cpus=24-31 \
-numa node,nodeid=4,cpus=32-39 \
-numa node,nodeid=5,cpus=40-47 \
-numa node,nodeid=6,cpus=48-55 \
-numa node,nodeid=7,cpus=56-63 ...

Thanks.
