Thanks a lot for the testing, I know it was difficult. At this point, I think the best way forward is to figure out what changes caused things to fail from -9 to -10. If you know how to build your own ubuntu kernels and bisect them using git to find where the first change causes a failure, then that would be a great way to start. If you don't know how to do that I can help you out. In that case, email me privately (<email address hidden>), and we can work through testing kernels. It will probably take around 8 kernels to figure out where the culprit lies.

Thanks again for all the thorough testing!
