How much memory do you have and who does the kernel accept that?
Look right at the top of dmesg for something like:

BIOS-provided physical RAM map:
 e820: 000000000009f000 @ 0000000000000000 (usable)
 e820: 0000000007f00000 @ 0000000000100000 (usable)
On node 0 totalpages: 32768
zone(0): 4096 pages.
zone(1): 28672 pages.
zone(2): 0 pages.

How many zones do you have?
