You won't believe it. After reinstalling, my macbook beeped as expected, but then the EFI reflashed by itself :D Probably the firmware file was still stored on my HFS+ partition.
However, i copied the entire /var/log so feel free to ask anything. I'm sending /var/log/syslog, /var/log/partman, /var/log/debug as requested before. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/774089 Title: Booting fails 3 times, works every fourth time after new install of Natty Narwhal amd64 on Macbook Pro -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
