I had the same issue and thought it had cleared up, but apparently not 
as I'm seeing exactly the same behaviour.  Here's a quantal bug I filed 
a while back that has been since marked fix-released:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1074589

As it's a suspend/resume issue, file a kernel bug:

# ubuntu-bug linux

I saw the issue in Quantal, it was fixed somehow in an SRU and now 
appears to be in Quantal again. I've also got Raring installed on the 
machine but have not played with it enough to see if this behaviour 
reproduces in Raring or not for me.
