I may be seeing something similar or related. I think I am seeing
a second sleep/suspend fail. Close the lid and it goes to sleep.
Open the lid and it wakes up. Close the lid again and it hangs.
I'll gather some evidence and report back, probably Monday.
uname -r: 2.6.34.6-47.fc13.x86_64
I had a similar problem with Lenovo T500 yesterday. It was not
reproducible reliably, and oddly the symptom is completely gone
today.
There is a bug report against kernel 2.6.34.6-47:
https://bugzilla.redhat.com/show_bug.cgi?id=629291
with a possible fix.
