Hi,

I believe this fix was picked up via bug https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1508133 ("Trusty update to 3.16.7-ckt18 stable release"). Upon examination of the lts-backport-utopic branch in Trusty, I see the following:

    commit dd9d3843755da95f63dd3a376f62b3e45c011210 upstream.

Can you confirm that users still experiencing an issue have updated to at least a linux-lts-utopic-3.16.0-52.70~14.04.1 or newer kernel?
