Comment 11 for bug 659149

This comment https://bugs.launchpad.net/ubuntu/+source/linux/+bug/658560/comments/7 confirm that patch from bug #647043 resolves your issue, therefore, resolving that bug will address your problems as well.

I can agree that using term 'duplicate' is not 100% right in this situation, the better name for relation would be 'depends on' or 'related to', but I don't think such options exist in Launchpad.

BTW. I marked 'duplicate' more bugs based on https://bugs.launchpad.net/ubuntu/+source/linux/+bug/663182/comments/9. IMHO it is easier to follow 1 bug entry with patch rather than 6. So maybe there should be new bug entry titled 'Kernel regression causing trouble for some Dell boxes' with list of the boxes and issues they have.
