I tested out linux- image-3.14.0-031400rc5-generic_3.14.0-031400rc5.201403022235_amd64.deb
I had the same boot issue. It would not boot, but if I set nr_cpus=1 it would boot up fine. It hands at the same "Booting SMP configuration" point as the older kernels. ** Tags added: kernel-bug-exists-upstream ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1284085 Title: unable to boot after install on 2013 macbook air To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1284085/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
