The MAC address changing pattern is interesting, there is a common address they will change into - 00:13:74:00:00:00 This looks like a HW issue, but I'm not very confident about it. Maybe not a big deal, but this issue would prevent these system from being selected into our SRU pool, the worse scenario is that this system is attached to a MAC-address-registered network (my dormitory network back into university require users to register they MAC address) ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: linux-image-3.13.0-32-generic 3.13.0-32.57~precise1 [modified: boot/vmlinuz-3.13.0-32-generic] ProcVersionSignature: Ubuntu 3.13.0-32.57~precise1-generic 3.13.11.4 Uname: Linux 3.13.0-32-generic x86_64 ApportVersion: 2.0.1-0ubuntu17.6 Architecture: amd64 Date: Tue Aug 19 06:00:11 2014 InstallationMedia: Ubuntu 12.04.5 LTS "Precise Pangolin" - Release amd64 (20140807.1) MarkForUpload: True ProcEnviron: TERM=xterm PATH=(custom, no user) LANG=en_US.UTF-8 SHELL=/bin/bash SourcePackage: linux-lts-trusty UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1358704/+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
