Thank you for your report and helping to make Ubuntu better. For future reference, if you could attach your log files as separate flat text files rather than zipped up tarballs, it would be much appreciated.
I wanted to let you know the Hardy Heron Alpha2 release will be coming out soon (around Dec 20). It will have an updated version of the kernel. It would be great if you could test with this new release and verify if this issue still exists. I'll be sure to update this report when Alpha2 is available. Thanks!
