Read what Andrea wrote. Quote from kernel:
case LINUX_REBOOT_CMD_HALT: notifier_call_chain(&reboot_notifier_list, SYS_HALT, NULL); printk(KERN_EMERG "System halted.\n"); machine_halt(); do_exit(0); break;
case LINUX_REBOOT_CMD_POWER_OFF: notifier_call_chain(&reboot_notifier_list, SYS_POWER_OFF, NULL); printk(KERN_EMERG "Power down.\n"); machine_power_off(); do_exit(0); break;
So if you see 'system halted' message, you did not ask system to powerdown. Fix your userland.
(Or, replace machine_halt() with machine_power_off() :-)
