Comment 11 for bug 330351

There have been many changes in Ubuntu since that time you reported the bug and your problem may have been fixed with some of the updates.
Has the patch been included and is the hang indeed fixed with it?
It would help us a lot if you could test it on a currently supported Ubuntu version. When you test it and it is still an issue, kindly upload the updated logs by running apport-collect 330351 and any other logs that are relevant for this particular issue.
