problem loading kernel module: " -1 Device or resource busy" error

[Vipul Jain]

Hello Everyone,

   I have written a simple hello world kernel module which compiles fine but
when I try to load
   it using insmod I am getting the following error:

    insmod: error inserting './cdd.ko': -1 Device or resource busy

   I was wondering if some body can please tell me what can be probable
reason for this error? or
   what does this error means.


Regards,
Vipul.
