[Colin Harrington]

This is also my experience with a MacBookPro 6,1 with the 12.04 release
(the MacBookPro6,1 is the 17" version of the MacBookPro6,2)

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

Status in “plymouth” package in Ubuntu:
  Confirmed

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
