You could try to change the memory model to "Sparese Memory".

Kernel type --->
 Memory model (Sparse Memory)  --->

My system memory only has 1 node of continuous memory. Any reason for that?

I try the hibernation feature with my MIPS box which has 128MB RAM.
After
boot up, it remains to have 110MB something. Then I mount ramfs on a

hibernation. The
process failed because of no memory. Then, I continue to cut the data
file
size and not success until 20MB.

I want to make sure if it is an expected behavior or I am doing some
wrong?
How large is your swapspace? Hibernation needs space on swap to store
the contents
of RAM (that cannot be loaded again from somewhere else).
