This is repeatable and as far as I know started about a week ago (possibly with the installation of 4.4.0-75). https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=856843 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1686099/+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
