hi Daniele,
Originally, I was registering and unregistering the devices similar to scull devices in chapter 3 of Rubini's book. That was working fine!
May be my problem has to do with the way I'm inserting and deleting the nodes from the link list since I am getting the device private structure from the link list.
Thanks for your help. J Kang

Hi J,
you should reformulate your question since its too generic.
Have you ever take a look at the excellent "linux device drivers 2nd edition"?
you can freely download and read from:
http://www.xml.com/ldd/chapter/book/
take a look at the Chapter n.3.
