Subject: PROBLEM: Keyboard not responding after resuming from
 suspend/hibernate

If I put laptop to suspend or hibernate by closing lid, power
manager or any other method and then I resume/wake up laptop, keyboard
is not responding. My laptop is a Sony Vaio VPCEH2F1E. 

Steps to produce bug:
1. Boot
2. Put laptop to sleep
3. Resume

What I expect to happen: Keyboard responds to key press.
What happens: Keyboard does not respond but mouse and trackball are
working.

git bisect point 9d659ae14b545c4296e812c70493bfdc999b5c1c as the first
bad commit.
