Hey, Ok, thanks. I see that in this second trace none of the processes are stuck, they are just taking a while to shutdown.
The information you suggested to me suggests that this is a new manifestation of a common shutdown bug where stopping down the various nepomuk processes would race against each other. This should have been fixed in the latest release, so my recommendation to you would be to update your nepomuk, akonadi, soprano and kalarm packages to the latest (4.10.1) version, when it becomes available next week. You will be able to get them from the kubuntu ppa as explained here: http://www.kubuntu.org/news/kde-sc-4.10 That should fix the slow shutdown, but to be clear, if your filesystem isn't unmounting properly, that's nothing to do with nepomuk - it's an ubuntu specific problem, and there's nothing I can do about it. Especially since you say it seems to happen even with nepomuk switched off.
