I think i found the reason for the bug because while checking out my dmesg i found out that isc-dhcp-server was respawning looply. So i tried removing it and now boot time is half.
Attached to this message there's the dmesg before removal. ** Attachment added: "dmesg.txt" https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/991909/+attachment/3122398/+files/dmesg.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/991909 Title: 12.04 boot is too slow To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/isc-dhcp/+bug/991909/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
