I have been watching this bug (silently) because I have exactly the same problem. However, it seems not yet to be fixed on my system. I am running the 11.3. default kernel (2.6.34.7-0.7-default). I could not really figure out how exactly to reproduce this bug. The described behavior appears - almost - always a few minutes after starting KDE. Sometimes it calms down again after a few minutes, sometimes the only way out is to kill udevd.
