Comment 73 for bug 1197451

On my Macbook air 6,2 (2013), Ubuntu 12.04.3 fails to boot and spils "blkid timeout" errors. It works better with 12.04.4, but the installation crashes on grub-efi-amd64-signed package. However, the audio is fine on 12.04.4, since the kernel is 3.11. Installing broadcom propertary driver will got stuck. Also that 13.10 solves most of the problems, but key "`~" maps to something else which makes it still unusable to me.
