I finally was able to figure out the culprid:

CONFIG_SLOB=y

instead of 

CONFIG_SLAB=y

--------
CONFIG_SLAB:

Disabling this replaces the advanced SLAB allocator and
kmalloc support with the drastically simpler SLOB allocator.
SLOB is more space efficient but does not scale well and is
more susceptible to fragmentation. 
--------

I was expecting a lower DMM performance but wasn't expecting such a
drain on kernel/network load.

The original reason for this change was a fixed flashmap and a increased
2.6 kernel that didn't fit in this region (backwards compatible).
