I wonder if this might be a dupe of LP: #1549494? We fixed that in xenial, but haven't backported the fix to wily. I haven't been able to reproduce this issue myself, but I uploaded a wily kernel w/ a backported fix to ppa:dannf/test, in case someone else can test it. It corresponds to the git branch here:
