[Bug 986149] Re: crash while booting MacBook Pro 6,2 from USB

[Jason Harvey]

Steve,

Adding break=top did prevent the graphics glitch, but I didn't get much
further. The system hung after probing the SCSI controller.

I should note that my coworker also has a MacBookPro 6,2, and his
machine booted and installed 12.04 without issue. So we might be looking
at a firmware or minor hardware difference that is causing trouble.

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
