how to freeze the 2.6 kernel on SMP m/c

[san deep <sandeep.albur@xxxxxxxxx>]

Hi,

Could you please suggest  how to freeze  the 2.6 kernel(SMP m/c) with
my own dlkm with  less number of code.

I tried the below mentioned code snippet, it hangs only the terminal
on which i executed the insmod command.
 Please correct the below code to freeze whole kernel.

#include <linux/module.h>	
#include <linux/kernel.h>	
#include <linux/spinlock.h>
#include <linux/delay.h>

int init_module(void)
{
	spinlock_t lock = SPIN_LOCK_UNLOCKED;
	while (1) {
        	spin_lock(&lock);
		msleep(100);
	 }
        //spin_unlock(lock);
	printk(KERN_INFO "Hello world :).\n");
	return 0;
}
void cleanup_module(void)
{
	printk(KERN_INFO "Goodbye world :(.\n");
}

Thanks and Regards,
Sandeep
