As far as I know, KDE employes the pm-scripts for hibernation and suspension. I have configured pm to use uswsusp. If i trigger pm-hibernate as root from the command line, the systems hiberates correctly using uswsusp. If I trigger hibernation using e.g. K->Leave->Hibernate I can not see the output of uswsusp, and the system does not correctly hiberante. It goes down in a way, that the disks have to be checked on the next boot.

The question is, how KDE invoces the hibernation. Is there more to in than just calling pm-hibernate? If so, could it be that the swap is turned off befor hibernation happens, and than failes because no swap is present?

I am glad for any hind

Yes, that is exactly the problem. upower disables hibernation if there is no swap space available even though some suspend implementations (e.g. TuxOnIce) does not require swap space. I had the same problem a couple of months ago and had to patch upower to workaround it.
