Comment 90 for bug 727620

No one has identified what patches fix the issue, if it is indeed fixed at all. The thing to do now is to test these kernels on more affected machines, and if it fixes the problem universally we can try to find the fix and backport it. You can get mainline kernels for Ubuntu from the following link:

  http://kernel.ubuntu.com/~kernel-ppa/mainline/

I don't know exactly what version 2.6.39-git19 corresponds to, but a 3.0-rc3 is definitely available. If you find a build that does fix the problem it would also be useful to move backward one version at a time until you find the last version that is still broken.

I'll also look to see if I can find out what changes might have fixed the issue.

Thanks!
