I saw there are alot of bugs but they seams to relate to older version and are closed, so i decided to file a new one? I run alot of machine with trusty an lxc containers but only these kind of machines produces these errors, all other don't show these odd behavior. thx in advance meno To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1403152/+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
