Hi,

When I "halt -p", lockdep warnings triggered as following (hand copy):

WARNING : at kernel/lockdep.c: 700 lookup_lock_class()

<snip>
lock_acquire
cleanup_workqueue_thread
workqueue_cpu_callback
notifier_call_chain
__raw_notifier_call_chain
raw_notifier_call_chain
__cpu_down
disable_nonboot_cpus
kernel_power_off
sys_reboot
<snip>

Regards
dave
