Comment 23 for bug 242713

OK, I've investigated and I was wrong about the version; 2.22.1-1ubuntu4.1 looks like it does have the fix (I'm on hardy).

I've looked at /var/log/kern.log and it seems bizarrely as though some of the suspend code ran after the resume (although I could see that the machine had a flashing light and was clearly suspended overnight) - I'll attach the relevant section here, as well as that from /var/log/messages (where you can see the gnome-power-manager messages)
