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?
