Can't see anything wrong with your module...Why would you name it kernel.c, its seems to me that's asking for trouble..

[darkrose0510]

Yeah, try renaming your module and file to anything but kernel, it should then work... also

printk("Hello world 1.\n");

should really be

printk(KERN_INFO "Hello world 1.\n");

but wouldn't be the cause of your problem here.

hi,

I think u should be in super user mode to insert module.Please check that ....

thanks
