Hi Windows team, 
My brother has a reproducible problem with both session restore and waking from sleep that causes his system to become unresponsive. If you're interested in digging in further, I can get you in contact with him.

OS: windows 7
Chrome Version: Stable

"""
When restoring my last pages after startup, or when waking up from sleep with Chrome open, after about 10 seconds, chrome becomes gradually unresponsive over another 10 seconds, followed by complete computer unresponsiveness. No changes in Memory or CPU usage on Task manager at the time; force quitting the application before it completely freezes also does not work.
