Memory needed for hibernation too much

   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 directory, create a file 100MB from /dev/urandom and enter 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).

I create a 300GB swap space (just use up the remaining space in disk, no special reason). Is that a problem?

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

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