I compared upstart's halt/poweroff implementation to sysvinit's, and there are a few differences which might be relevant. After #define translation, the halt/poweroff bit in sysvinit does:

  reboot(RB_ENABLE_CAD);
  kill(1, SIGTSTP);
  if (do_poweroff)
    reboot(RB_POWER_OFF);
  reboot(RB_HALT);

The fallthrough appears to be deliberate; RB_ENABLE_CAD seems at least useful; and is it possible that the kernel's getting stuck before poweroff because init hasn't been SIGTSTPed?
