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

[Steve Langasek]

So if it hangs after probing the scsi controller, I think the issue
we're looking at here probably has nothing to do with plymouth - I think
you just happen to have garbage on the screen because the crash is
happening while plymouth is set up.  So let's reassign this to the
kernel.

** Package changed: plymouth (Ubuntu) => linux (Ubuntu)

** Changed in: linux (Ubuntu)

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

Status in “linux” 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
