Can you capture a digital image or screen capture of the failure your seeing and post it to the bug.
It sounds like we are seeing two bugs here. First is the system won't boot without smp. The second is that a regression was introduced in v3.10-rc1 that prevents the system from booting even with smp. Let's focus on the second bug first and possible open a new bug for the first. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1213795 Title: newer kernels (3.10+) don't boot on MacBook Air 6.1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1213795/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
