Comment 161 for bug 852190

The patch from the Linux bugzilla is currently working its way to Ubuntu through the stable kernel releases. If that patch really does fix the issues then it should be fixed in the official Ubuntu kernels in 3-6 weeks, and sooner than that in raring.

For now I've done a test build of the raring kernel with that patch. Please give it a try let me know whether or not it fixes the issues.
