As Christoph found, this memory map is really strange. Other machines
have something like

Zone PFN ranges:
  DMA             0 ->    16384
  Normal      16384 ->    16384
early_node_map[2] active PFN ranges
    0:        0 ->     8192
    1:     8192 ->    16384

Lucio,
What code builds the memory map that gets passed to the kdump kernel?
Does the original kernel see the same map on your machine?
