Pavel, I have two nearly identical Kubuntu-5.10 notebooks here, both of which work perfectly with suspend-to-RAM and just about everything else. Both of them also did swsusp until today. Now one of them fails, but the other still works. The one that failed was just upgraded from a 2.6.12-based kernel to the stock 2.6.16-rc6-git7, same kernel as the one that works. I instrumented the swsusp code to try and see why it fails, and here (attached) is the result. It's skipping over the swap partition for some reason. Why? Cheers
