[Bug 1039762] Re: freeze during Quantal install with USB non persistent key

[Carla Sella]

I created a USB non persistent key with today's  Quantal daily ISO (http://cdimage.ubuntu.com/daily-live/20120922/quantal-desktop-amd64.iso) but on boot I first saw the white ubuntu logo on the purple backgraound but suddenly the screen got all messed up, see attached picture, I heard the sound you hear when Ubuntu starts.
After getting the messed up screen I could not carry on installing as it was impossible to see anything.

  freeze during Quantal install with USB non persistent key

Bug description:
  I downloaded this iso: http://cdimage.ubuntu.com/daily-live/20120821/quantal-desktop-amd64.iso for installing Quantal on a second partition of my PC to carry out some tests, but during boot of the non persistent USB key (created with Startup disk creator) the boot of the USB key stalls.
  I tried to download the iso twice and checked the md5sum.
  I had the problem twice, first time had only a black screen and had to type ctrl+alt+f1 to get some information with ubuntu-bug and the second time got some output on a black screen but had to press ctrl+alt+f1 to launch ubuntu-bug.
  I'm attaching the apport info of the second try.
  I tried to install on this hardware: http://wiki.ubuntu-it.org/CarlaSella/lshw.
