I'm not sure that someone is me!  But, Toni, just to check, can you tell
us whether the boot menu at which you selected was text mode (GRUB) or
graphical mode (syslinux/gfxboot)?  The graphical one shows the Ubuntu
logo and has F1-F6 menus across the bottom of the screen.

Title:
  crash while booting MacBook Pro 6,2 from USB

Status in “plymouth” package in Ubuntu:
  New

Bug description:
  reproduce:

  1. Create bootable USB flash drive with "Startup Disk Creator" from image "ubuntu-12.04-beta2-desktop-amd64.iso"
  2. Boot MacBook Pro 6,2 from USB flash drive (hold "Option" while truning on, wait 30 seconds, select drive)
  3. Select "Try Ubuntu without Installing"
  4. Hit "Enter": after a few seconds a distorted screen appears, some pixels are changing rhytmically beween red and green, then nothing happens anymore

  
  remark:

  I tried both a SanDisk Cruzer 2GB and Hama 8GB: same behavior
