We started a Reverse bisect in comment #17. However, it appears the hardware is no longer avaiable.
As mentioned in comment #22, this is fixed in Yakkety. You could use that kernel, but if you can reproduce the bug, we can continue the reverse bisect? That would allow us to identify the commit that fixes the bug, and have it SRU'd to Xenial.
