Title:
  Ubuntu 12.04 and 11.10 fails on resume with ASUS PZ58 & ATI Radeon
  4650

Status in linux package in Ubuntu:
  Expired

Bug description:
  The desktop correctly goes to suspend, with fans silenced, audio
  turned off and screen output stopped. Neither the keyboard nor mouse
  (USB both of them) are able to wake the machine. On attempting to
  resume with a single short touch of the power button, the fans spin up
  to full speed and stay spinning at full speed, the power light comes
  on as expected, however the screen remains black and there are no
  lights on the keyboard. Moving the mouse or pressing keyboard keys
  does nothing.

  Did the machine break while going to sleep or waking up?
  - Waking up (resume)

  Is it reproducible?
  - Yes on 10 out of every 10 sleeps, it failed to resume

  Did it work before?
  - Never on this ASUS PZ68 desktop (Intel i5 2500, ATI Radeon 4650 -> dual head Samsung Syncmaster943s)
  - It does perform correctly on my Ubuntu 11.10 laptop (Acer Travelmate 5720)

  Do you end up with flashing Caps Lock light or similar?
  - No kernel panic indicators whatsoever. No lights on keyboard whatsoever. No screen output either screen (and no boot screen, no GRUB)

  The computer does not reboot until forced by holding down the power
  button etc.

  (See attached text file for dmesg output etc.

  --- UPDATE 20/05/2012 ---

  Problem persists with 12.04, exactly as described. Not yet fixed.
