Laptop sleep gone bad in Gutsy

[Avi Schwartz]

I upgraded my Dell D820 yesterday from Feisty to Gutsy and since the 
upgrade, waking the laptop from a sleep is iffy at best.
With Feisty, waking the laptop from sleep was almost 100% reliable.  
With Gutsy, the chance of the laptop properly waking up is about 50%.  
Sometimes it wakes up and in other times it starts waking and then 
suddenly it powers down.  I can no longer trust putting the laptop to 
sleep which is a shame since it used to work so well.

Any ideas what should I look for?

This is what I found in the log with a strange entry in the 4th line 
saying that suspend failed:
