Joseph Salisbury, I installed the test kernel and booted several times. Still hangs after the "Initial RamDisk loaded" message is shown and the fan speeds up. The screen however does stay alive and doesn't switch off or turn black (messages stay visible).
Hope this helps. If you tell me where to look, maybe I can provide some logs or something. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1455852 Title: 15.04 will not boot on MacBook 2,1 Status in linux package in Ubuntu: Incomplete Bug description: see: http://ubuntuforums.org/showthread.php?t=2274999&p=13286624#post13286624 Lubuntu 15.04 on refit grub dual boot macbook 2,1 linux-image-3.16 will boot, though sometimes hangs but, reboot will work eventually.
