Title:
[MacBookPro8,1] Fails to boot without noefi since linux-
image-3.13.0-20-generic
Status in “linux” package in Ubuntu:
Triaged
Bug description:
My MacBookPro 8,1 (Early 2011, 13") will not boot using any trusty kernel
linux-image-3.13.0-20-generic or later. I get a grey rectangle displayed,
centred, filling most of the screen, and the system hangs. When booting into
rescue mode without kernel parameters quiet, splash, vt.redirect, etc., I would
see something like:
> Loading vmlinuz-3.13.0-27-generic...
> Loading initrd.img-3.13.0-27-generic...
Then the system hangs. When I reboot I'm dropped into the GRUB menu.
To boot in EFI mode, I keep linux-image-3.13.0-19-generic around - which
works fine.
WORKAROUND: Booting using kernel boot parameter noefi, however gfx and
disk performance suffers, and features such as the monitor brightness
keys fail to work altogether.
