Bug 155102

Description of problem:
The laptop won't set up IDE from a S3 suspend.
Keyboard and mouse input ok, all fine but the hda seems to have trouble
recovering (hda led blinking hard), can't execute any command because the hda is
not accessible. Kernel outputs DMA timeouts for the hdd...  After half a minute,
decides it can't set up, and goes for a controlled shutdown.

Version-Release number of selected component (if applicable):
Since ACPI exists

How reproducible:
Always

Steps to Reproduce:
1.Suspend to S3. 
2.The power LED blinks. 
If I press the power or specials button, it restores graphics, keyboard
and mouse are working but hda has problems.
3.Goes to controlled shutdown after a minute
  
Actual results:
Goes to controlled shutdown after a minute

Expected results:
Resume on S3 suspend

Additional info:
The same happens with Ubuntu Hoary:

This is Matthew Garrett's comment:
"Linux currently has no real support for setting up IDE interfaces on resume.
Some machines are kind enough to set the IDE interface up themselves, but on
others we're doomed to failure. I'm looking into implementing this, but it won't
happen until some time after Hoary."
