My problem is similar to this one. I tried fresh installing Ubuntu 11.04 over 10.10 on my MacBook Pro 5,4 with the ubuntu-11.04-desktop-amd64.iso image. Only it never boots successfully. On every fourth (or so) time, I get an "invalid arch independent ELF magic" error. It looks like the fix for this is to get to a bash prompt upon successful boot and reflash the EFI firmware with this bless command. But how am I supposed to do that when I can never get a bash prompt?
