Public bug reported: This is related to bug 772834 and has the same symptoms on a different hardware setup.
When trying to enter into suspend mode the screen goes black, with the LED backlight still on, and the fan spins up at which point the system appears to hang. I am unable to switch to either a terminal prompt or back to Unity (Ctrl+Alt+F7). I have tried adding the pcie_aspm=off command to the grub boot args and also removing the xhci_hcd driver before going into suspend. Neither have helped, although there is a slight difference in behaviour. Without removing the xhci_hcd driver the HDD light remains lit, buy removing it first and going into suspend the HDD light eventually goes off. I will post more information from apport.
