Some time back I had hibernation working (most of the time) properly on my 12.04.
Had to reinstall recently and now I am quite happy with my system. However, the hibernation does not work. The only notable difference from my former 12.04 install is that I have RAID-connected SSDs (had 2x128, now 1x256) and that I am using XFCE over Gnome.
Is it worth trying to upgrade to 12.10 or 13.04 in order to get hibernation to work? Could it be caused by RAIDing? I'd love to have hibernate working properly.
Currently I'm at a 64bit 12.04 on a Sony Vaio Z21V9E/B.
