Comment 13 for bug 1167622

I've tried both. http://kernel.ubuntu.com/~jsalisbury/lp1173423/ works for me but http://people.canonical.com/~jsalisbury/lp1173423/ doesn't.

Doing an strace on efibootmgr in the current Ubuntu kernel (3.8.0.22) it seems that the software isn't too savvy on errors. It ignores a "device full" error when trying to create an addition boot entry (caused by the notorious 50% fix) and fails later on trying to right boot order data.
