Public bug reported:
The 12.10 alpha 3 amd+mac iso from
http://cdimage.ubuntu.com/releases/12.10/alpha-3/ will only boot after
setting acpi=off.
At the man+keyboard screen, press any key and accept English, then press
F6, then move to acpi=off and press Space to select it, and Esc. Then
press Return to allow the LiveCD to boot, which takes about 3 minutes.
This is on an iMac 5,1, Core 2 Duo, 3Gb RAM, ATI Radeon.
