I am happy to report that the reflash reported by sirblackheart in #17 worked for me too! I pretty much followed the instructions in the post, after I shutdown the mbp and start again, the grey update screen appears, progress bar runs through then the computer resarts and things seem to work (this is the first restart ... but it worked right away).
@Garbriel: If I can assist with any additional information, please let me know. I used the same image as you. The 'bless' command described in the blogpost returned without any error message. I then shutdown the computer, powered on again, waited about 10s, then the grey screen that you posted appeared, the progressbar ran through (about 5s I would say), then the computer resarted and now everything seems to work again. This is on a macbook pro 5,5. @sirblackheart Thank you very much for digging out that post, you were very helpful!! I think we should go to the blog poster and thank him too! -- You received this bug notification because you are a member of Mactel Support, which is a direct subscriber. 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 Status in Ubuntu: Confirmed Bug description: Dear all, I am experiencing a severe problem after a new install of Natty Narwhal on my Macbook Pro last night: The install worked fine, but after reboot nothing came up except fo a black screen. After forcing the machine off and on multiple times I was able to bring up the rEFIt boot menu by pressing and holding the 'Alt' (or Option) key and I can then boot into MacOSX or Ubuntu without a problem. After restarting / powering off I then have to turn the computer on / off the same number of times (3 or 4, I don't remember exactly) where nothing happens until it works again. I am using a MacbookPro 5,5 (13.3 Inch). My harddisk is setup as follows: 200MB Partition for EFI 20GB Partition for OSX 18.6 GB Partition for / (ext4) 108.49 GB Partition for /home (ext4) 1.86 GB Partition for swap Other people also seem to experience the same issue: http://ubuntuforums.org/showthread.php?p=10743955&posted=1#post10743955 This is a pretty big problem for me, so your help is very much appreciated.
