@Imre Kaloz : ok so you think it's a real issue in the kernel (and not an issue in my grub config)? I'm going to check it by installing a 3.8. If it's boots then yes it's an issue in the kernel.
I would be happy to help to debug this potential kernel issue but what can I do as the boot process get stuck as early as "Loading initial ramdisk"? Is there any boot options related to UEFI we should try? (sorry I'm a fresh man when it comes to UEFI related issues). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1197451 Title: Ubuntu fails to properly boot on Macbook Air 2013 6,1 & 6,2 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1197451/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
