Actually it is working but is far from what should be expected. After initiating hibernation (suspend to disk) screen turns blank and it spits out some info (included in dmesg.log) than X session turns back in. After 10-15 seconds computer gets sluggish and after about 20 seconds it turns off showing some more information.
