Comment 15 for bug 455112

I have the same problem of virtualbox being unusably slow since I upgraded to karmic, in jaunty everything was runnig fine. I also noticed that gkrellm lags every 4 seconds for 4 seconds. During these the window doesn't get updated. Other programs run without problems however.

Installing the rt-kernel as suggested in http://forums.virtualbox.org/viewtopic.php?f=7&t=23978 worked for me, so this seems to be a kernel problem. The strange thing is that except virtualbox and gkrellm everything is running fine...

I'm on a MacbookPro5,5 (Core 2 Duo IA64).
