Title:
  booting with amd64 kernel and completely i386 userland is unstable
  during the system upstart

Status in linux package in Ubuntu:
  Incomplete
Status in upstart package in Ubuntu:
  New

Bug description:
  I wanted to run my 14.10 (Utopic) i386 system with the amd64 kernel,
  so I added that architecture and apt-get-installed the amd64 linux-
  image and linux-image-extra (I learned this was possible thanks to the
  advice at http://askubuntu.com/a/635774/19753 ).

  However, the system upstart procedure more often fails than not: it
  fails by rebooting the computer. (Only around 1 time of 4 is
  successful.)

  A limited system start is (probably, always) successful: either with
  init=/bin/bash parameter to the kernel, or choosing the recovery boot
  option. (However, if I "resume" from the recovery menu, or run "exec
  init" in bash, then the upstart procedure is similarly unstable: it
  usually fails/crashes and reboots.)

  I checked my suspection that  the video driver (nouveau) and X might
  be involved, but that turned out not true: the upstart procedure is
  similarly unstable with "nomodesetting" kernel parameter and without,
  booting into runlevel 3 or the default one.

  Perhaps, I'd like to debug the upstart procedure step-by-step to
  detect which step makes the system crash and reboot, but I don't know
  how. As concerns the timing, the moment the reboot happens can be
  different: it can happen rather early (when I see the message about
  activating the swap) or much later.

  If the system upstart procedure has completed successfully, then it
  works in a quite stable manner and doesn't crash/reboot. So, there is
  something bad specifically during the system upstart procedure.
