Lubuntu vivid amd64 2015-01-28 does not boot

[Lars Noodén]

Lubuntu vivid amd64 2015-01-28 does not boot on a MacBookPro from USB stick. I put in the USB stick an hold down alt while powering up the computer. Then the choice of boot media comes up, and I select the USB stick.

Here are the hardware specs

Here is the image which does not boot:
http://iso.qa.ubuntu.com/qatracker/milestones/326/builds/88376/downloads

The image starts in "insecure mode" and then GRUB comes up and offers several choices. When choosing "Try Lubuntu without installing" it runs for a few seconds and then freezes, apparently indefinitely. There is no way to get to another console with ctrl-alt-f1 or anything else. The only text on the console is:

[ 7.093063] i i8042: No controller found
starting version 218

More or less the same error occurs when choosing "Install Lubuntu" from GRUB

What should have happened is that the installation proceeds or else the Live session starts, depending on the choice in GRUB.
