Ok, it's what I expected.
This isn't a bug. You need to use the PAE kernel to use all your memory.
This is your memory map:

The line at the bottom is important.
0x000000015C000000-0x0000000100000000 = 1,543,503,872
So that's where just over 1.5 GB of your memory is mapped. Note that the
address starts at 0x100000000 - which is the next address above the 32-bit
address space. The -default kernel can't access memory above that. It's why the
-pae kernel exists at all.
As for your remaining memory, it could have just been occupied by device
mappings. I'm not going to dig any deeper though as the right answer is to use
the PAE kernel.
Closing as INVALID.
