I am currently getting these on 4.4.0-66, on 14.04LTS / trusty. Xen VM. Unfortunately unable to migrate immediately to 16.04LTS (largish platform with many custom packages built for the distribution). On the 3.13.0 kernels I don't get these, but would like to go to 4.4 due to other fixes being present there.
