Created attachment 63156 [details] Screenshot of the busy machine running nothing but rsync Version: 4.6 (using KDE 4.6.2) OS: Linux The attached screenshot shows the state of my computer during a simple rsync from the internal HDD to an external HDD. To the left top corner, you can see in the performance widgets that the actual CPU is 100% on my 2-core processor. However, the "task manager" shows only minimal CPU action. Before the screenshot, several programs were run and quit. At the time of the screenshot, the only active user process was rsync, but the computer was so busy that it had even problems moving the mouse cursor (jumping cursor due to overload). The phenomene happens often when I multitask and keeps going for several minutes even though I closed the programs. Mostly, the next boot of the computer is very slow and sometimes, it crashes. Reproducible: Sometimes Steps to Reproduce: Multitask on Plasma Actual Results: Computer busy, but no process seems to be responsible Expected Results: Possibility 1: Show in the "Task-Manager" what process is slowing the machine down Possibility 2: Not being busy.

I'm sorry, but I don't understand the 559 comments behind that link. They're insulting each other and talking about VANILLA, but as I have even no precise idea what a kernel is, there's nothing I can do with that "Computer-Chinese"... sorry, but is there a solution for linux beginners?
The Linux kernel is the part of the system that is responsible for managing CPU, disk, and memory resources. "Vanilla" means the kernel without any distribution specific patches, because often kernel developers think bugs are introduced by those patches. There is no solution other than waiting for this most hated Linux bug to get the FIXED status. Sorry, but it isn't a KDE problem. If you need instructions to work around it, please ask in a Linux forum, such as http://ubuntuforums.org/
Got it. Thanks a lot.
