Thanks for the update, Junien. Now we know the fix is in the upstream v4.8-rc8 kernel. Then next step is to identify the commit that fixes this bug, and then SRU it to Xenial.
It would be best to next step the latest upstream 4.4 kernel. That will tell us if the fix was already sent to upstream stable. If it was not, we will need to test some other upstream kernels to narrow down further when the fix landed in mainline. Can you test the upstream 4.4.23 kernel?
