I recently upgraded to the Kubuntu Natty Beta 1 and I've been having a lot of issues with the process kworker. At moments it uses almost half my CPU. Also, strangely enough it seems to affect my USB ports; whenever I plug in an USB drive, the process kworker goes into hyperdrive, leaving me unable to work.

I have thought about filing a bug but since I haven't even found any reasonable explanation on what kworker is I figured I should find out first.
