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.
