Too many work arounds suggested in #1308264 as well in internet nothing helped VERSION 14.04 (trusty) Kernel Version 3.19 * 4.2 * Works fine with lts-utopic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1602238/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
