Public bug reported:

Description:    Ubuntu 14.04.2 LTS
Release:        14.04
Kernel 3.13.0-48-generic

I expected to be apple to boot to the password prompt for my encrypted root (and beyond) with correct graphics.
Instead I found that my keyboard was not recognised after grub, so I am not able to decrypt my root or login 

More detailed explanation:

I have Ubuntu installed on my 17'' core-duo intel imac, with an encrypted root partition.
Version 12.04 with kernel 13.5.0-17-generic worked ok, but I updated to the LTS version 14.04.
The system now freezes before asking for my encryption password when booting (I am using EFI with grub2)
with my old kernel (13.5.0-17-generic) and with no args on the kernel command line. If I put nomodeset the boot
progresses to the encryption password and I can successfully login, however the video is completely scrambled (I literally cannot
make out anything). Having tried many ways to fix the video, I tried the latest kernel (3.13.0-48-generic). In this case
the boot gets to the password and the graphics appear to be ok, but the keyboard/mouse do not respond. Again I tried many fixes, unsuccesfully. I installed the extras so as to have usbhid, mac_hid etc, and found that the behaviour now reverted precisely to that outlined above for 13.5.0-17-generic; that is scrambled graphics but successful login (with nomodeset), and freezing before
reaching the password prompt (without nomodeset).
I tried manually adding only the hid modules to my initrd.img-3.13.0-48-generic built prior to install of extra, but found graphics again ok but still no keyboard !

This report was made via a ssh session after booting with the scrambled
video.
