Title:
  System doesn't resume on suspend. Shutdown doesn't complete

Status in linux package in Ubuntu:
  Expired

Bug description:
  Version:
  Ubuntu 11.10
  Release 11.10

  Package Responsible:
  Unknown. Possibly the kernel or pm-utils

  What was expected:
  System resumes normally after suspend.

  What happened:
  When resume is triggered (either by lid opening or key-press) Fan speeds up, and the system appears to freeze. I have to manually power-off (by holding down the power key) and reboot.
  When the system freezes during resume, emergency key-combinations like ctrl+alt+delete, ctrl+alt+backspace, ctrl+alt+printscr+K  dont work. And not even the ctrl+alt+printscr+ R,E,I,S,U,B sequence.

  Frequency: Everytime i resume

  Additional Note: Resume worked a while ago, its a recent happening. The changes i made were:
  Installed the fglrx driver, and uninstalled it. Deepin software center performed an auto-update (possibly) Not sure what updates were applied.

  Steps to reproduce:
  1) Suspend the system
  2) Wait for a while after the power button starts blinking
  3) Press any key

  Alternately:
  1) Close the lid
  2) wait for a while
  3) Open the lid.

  Specifications of my laptop:
  Manufacturer :HP
  Series: Pavilion g6
  Processor: Intel i5
  Graphic card: AMD Raedon (Not sure of further details)
  Kernel version: 3.0.0-16  (GRUB entry has this. Must be kernel version)

  Additional Notes: 
  Shutdown freezes the system with ubuntu logo on screen

  On starting, BIOS shows a thermal shutdown warning ( It was there
  since i installed ubuntu. Shouldn't be related.)

  On resume, capslock led is on all the time. LED at network port (Lan
  cable) blinks. the red-one, presumably indicating data transfer.
  there's also a white one thats always on when the cable is connected.

  I use "acpi_backlight=vendor pcie_aspm=force" to make brightness
  control work and to optimize power consumption.
