Comment 96 for bug 774089

Same thing here. I installed ubuntu 11.04 before without problems, but when i reinstalled it because i messed up some configs in ubuntu the bug appeared. For me, the efi backup is stored in /dev/disk0s1, can i use an update app from another cd? and is it, that this is really a backup, or is it just the efi damaged by ubuntu? the firmwareupdate seems to be a bit dangerous, because nobody can say if i brick my macbook completely with it, so i think i'll live with it until there is a robust solution to this, or an official firmware update for macbook6,1 is released.
I also want to say that I didn't read the release notes, so even if there was a hint about this bug i would not have known, shame on me. But since the installation is very macbook friendly and it knows when it is installed on a macbook, there should really be a disclaimer there!
