The issue is still present even after upgrade to 14.10. The problem is that system sometimes does not suspend correctly. After initiating suspend the display is being turned off completely, HDDs are being stopped, but fan remains ON and the PC LED also stays on. The only possibility is to make hard reset using the HW button on the pc. Pressing power button will neither suspend/turn off computer nor turn in on again. I can reproduce this issue randomly - approximately 1 out of 5 suspends will fail. It looks first suspend after reboot will always work fine. Then some of the suspends after successfull resume will fail (randomly). I also tried fresh install of Ubuntu 14.10, but the suspend kept failing as well. Checking /var/log/pm-suspend.log did not help me as there is always "performing suspend" message either after correct suspend or failed suspend.
