The underlying issue was that this was booting in CSM mode and the x2apic wasn't being configured correctly causing an SMP boot to hang.
We solved this issue by using the EFI grub loader to avoid booting in CSM mode. 1. add /boot/efi /etc/fstab 2. install grub-efi running grub-install --target=x86_64 and reboot. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1322148 Title: [MacBookPro11,1] Utopic freezes on boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1322148/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
