Kernel timers problem

["vaishali paisal" <vaishalipaisal@xxxxxxxxxxxxxx>]

  Hello,

I have written a kernel module that uses kernel timers.If i don't declare the variable mytimer as static the system hangs.But if i give it static then it works when i call function set_timer only once ,if i call it multiple times then the system hangs.I am unable to locate the fault

the code goes like this:

#include<linux/module.h>
#include<linux/kernel.h>
#include<linux/init.h>
#include<linux/sched.h>
#include<linux/timer.h>
void timer_timeout(int c)
{
struct timeval timecount;
do_gettimeofday(&timecount);
printk(KERN_INFO "\ntimer%d expired at :%ld seconds %ld microseconds",c,timecount.tv_sec,timecount.tv_usec);
}
                                                                                                                           
void set_timer(void)
{
    static struct timer_list mytimer;
    static int i=1;
    struct timeval timecount;
    init_timer(&mytimer);
    mytimer.expires=jiffies+2*HZ;
    mytimer.data="">     mytimer.function=(void*)timer_timeout;
    add_timer(&mytimer);
    do_gettimeofday(&timecount);
    printk(KERN_INFO "\ntimer%d started at :%ld seconds %ld microseconds",i++,timecount.tv_sec,timecount.tv_usec);
  return;
}
                                                                                                                           
                                                                                                                           
int time_init(void)
{
    set_timer();
    return 0;
}

void time_cleanup(void)
{
  printk(KERN_INFO "\ntimer unloaded\n");
}
module_init(time_init);
module_exit(time_cleanup);
