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. The system was unusable with the default one
I would be glad to provide any logs and information you need for resolving the issue. By the way I have 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.
