I can confirm My Macbook 6,1 has also suffered from this bug.. I have to power cycle it 5 times before it will boot. But on a plus side.. it does boot.
I do have an issue in that Apple do not have any updates for the efi on my model on its web site. So my choices are, live with it or replace the logic board at cost... I have emailed my local Apple service centre requesting a copy of the firmware of at least a chance to pay them to re-flash my Macbook. But I am not hopeful. I dont think Apple will be too interested in fixing the result of a bug in Open Source. I am very disappointed. And whats the most disappointing is the release notes had not been updated with the details of this issue before I attempted (a week back) to install Natty. If it had been I would not be in this situation. PS: I just checked the release notes and there is still no warning about this issue. -- 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
