Hello everyone, I also have the issue on a Thinkpad T500. Rolling back to 2.6.35 did not solved it, but on 2.6.34 I don't have the issue. upgrading to 2.6.39-02063903 also did not solve the issue. however on my laptop it is quite better than the with the default kernel in natty. The system was unusable with the default one. The issue also exists in Maverick with kernels older than 2.6.35
I also opened a bug uploaded also about the same topic: it can be related to this I guess: Bug #772704 I may think that it may somehow related also to the wifi card/driver, as usually during these periods when kworker eats up my cpu (it uses more than 50% of the cputime) the system often dropped from the wifi access point as well. If anyone has a solution, it would be great to have, as this is a really annoying issue, and makes working impossible on the system.
