Public bug reported:
My MacBookPro 8,1 (Early 2011, 13") will not boot using any trusty
kernel linux-image-3.13.0-20-generic or later, unless the noefi kernel
param is set.
When booting linux-image-3.13.0-20-generic or later without the noefi
param, I get a grey rectangle displayed, centred, filling most of the
screen, and the system hangs. If booting into rescue mode without noefi
(i.e. without quiet, splash, vt.redirect, etc.), I see the following
(roughly, from memory...)
> Loading vmlinuz-3.13.0-27-generic...
> Loading initrd.img-3.13.0-27-generic...
Then the system hangs. In either case, on reboot I'm dropped
automatically into the GRUB menu.
To boot in EFI mode, I keep linux-image-3.13.0-19-generic around - which
works fine. Booting a latter kernel works if I specify noefi, however
gfx and disk performance suffers, and features such as the monitor
brightness keys fail to work altogether.
