Hi Martin,

thanks for your suggestions.

Since the system rebooted after such crash usually, I wanted to use
netconsole (as described at
https://wiki.ubuntu.com/Kernel/KernelDebuggingTricks#Network_Console ),
but I didn't see any messages on the network, probably because the
netconsole module has to be loaded (and added) in the initrd. Will look
further into how to enable it...

(BTW, probably, by chance, with these added parameters (debug and
netconsole), the system has just booted successfully.)

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

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.
