The system wont suspend / resume

System Hardware     Homebrew system
Motherboard         Gigabyte Z77-DS3H Revision 1
Bios version        F8 updated to F9
Processor           Intel I5-3770K 3.4G
Ethernet            Atheros AR8161 (Rev10) 
Graphics            Intel HD4000
Memory              8G (2 X 4G) Corsair 1600Mhz
CD/DVD              Pioneer DVR-20BK
Multi card reader   Icybox 4 x USB2,  2 X USB3, 1 x Esata + card slots      
Power supply        Winpower-SL8460BTX (450W)

OS                  Xubuntu 12.04 with backports to provide Atheros drivers

The mains lead plugged in via a power meter. The system “ticks over” at about 50W When I select the “Suspend” option from XFCE

  1. The hard disk drive stops
  2. The processor fan stops
  3. The power LED goes off (NOT TO SLOW FLASH)
  4. The power consumption drops to about 4W

If I press a keyboard key during the first minute the system restarts nomally

If I wait longer than one minute before pressing a keyboard key

  1. The hard disk drive restarts and the access led blinks
  2. The processor fan runs
  3. The power led comes on
  4. The power meter reads 80w but falls to 50ish after a few seconds

The graphics do not show any signs of life If I press caps lock or num lock the keyboard led does not respond. Nor does alt -F1 etc. There is no response to the reset button

I have tried many things including

  • Updating to the latest bios (F9)
  • Disabling the onboard network, sound and all unnecessary usb ports in the bios
  • Booting with “noacpi”, “acpi=off”, “noacpi” and may other combinations.
  • Booting with Ubuntu 13.04 live editition
  • Fedora 18 live edition

The results are always similar. I look as though the suspend process fails to complete (no power LED slow flash)

Any help would be much appriciated

I have appended my “pm-suspend.log” file below
