[Joseph Salisbury <joseph.salisbury@xxxxxxxxxxxxx>]

I built a new test kernel with a cherry pick of commit a212116.   It can
be downloaded from:

http://kernel.ubuntu.com/~jsalisbury/lp1561974/

Can you test this kernel and see if it resolves this bug?

If it does, I'll submit a SRU request to include the commit in Xenial.
