Title:
  System crashes during boot to single user mode using nvidia graphics

Status in “console-setup” package in Ubuntu:
  New

Bug description:
  Caveat: I can't definitively narrow this bug down to console-setup, as
  I'm having trouble figuring out how to keep it from running on boot.
  However, here's the evidence I've got to indicate it's console-setup's
  issue.

  Boot with "recovery" on the kernel command line:  This works, I get
  the recovery menu and can drop to a shell.

  Boot with "single" on the kernel command line: This does not work,
  system hangs immediately after printing "fsck from util-linux 2.19.1".

  If I switch the BIOS into Intel graphics mode (not a useful
  workaround, this machine has a significant 3d graphics load during
  normal use), I can boot to "single" just fine, and the console text
  mode changes (which does not happen during the crashing "nvidia" boot,
  nor does the console text mode change when booting with "recovery").

  So if it's not in console-setup, it's close by.  Any suggestions on
  how to ensure that the video hardware does not get messed with until X
  starts are appreciated.  (X seems to work just fine).

  Thanks.
