I have verified that clearing out most of the dynamic content relying on Internet-facing connectivity from update-motd.d and adding /sbin/stop rsyslog to rc.local does solve the bug.
I suspect the problem with rsyslogd spinning at 100% cpu is a regression from Lucid, where kmsg is only accessible to root, but the process is running with reduced privileges and not detecting the problem. # mount -o loop precise-server-cloudimg-amd64.img /mnt # cd /mnt/etc # vi rc.local add /sbin/stop rsyslog to rc.local # cd /mnt/etc/update-motd.d # rm 90-updates-available # rm 91-release-upgrade # rm 98-reboot-required -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1028682 Title: precise uec builds eat 100% cpu on launch, check-apt and rsyslogd To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1028682/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
