Two things that might cause the hang. 
First, memblock_add() is called after node_min_pfn has been rounded down to
the nearest 8Mb and in your case this cases memblock to see more memory that
is actually present in the system.
I'm not sure why the 8Mb alignment is required, I've just made sure that
memblock_add() will use exact available memory (the first patch below).

Another thing is that memblock allocates memory from high addresses while
bootmem was using low memory. It may happen that an allocation from high
memory is not accessible by the hardware, although it should be. The second
patch below addresses this issue.

It would be really great if you could test with each patch separately and
with both patches applied :)

Tested separateöy and together, with the previous debug patch applied.

debug+patch1 caused no visible change cmpared to just debug - same crash before starting init as with plain debug patch.

debug+patch2 caused a change - now instead of hang before starting init, it hangs after starting init as with no patch applied.

debug+patch1+patch2: works, dmesg attached:
