I understand given your setup you may not be able to do this however, if it were possible for you to test with the latest development kernel that would be helpful.
Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds .
