My desktop PC did not support for hibernate on Ubuntu 14.04. Therefore, I installed TuxOnIce (kernale 3.13.0-36-generic-tuxonice) to enable hibernate feature. Now, the hibernate feature works fine on low memory use (with command pm-hibernate).
But, when I hibernate my computer with too many applications open (higher memory use, > 45% of total memory), I am getting error message saying seeking to free XXXXMB of memory.
I have a SWAP memory which is bigger than RAM memory, here are the details of my PC memory status:
total used free shared buffers cached
Mem: 16018 10577 5441 77 211 3151
