Hi Srinivas, Thank you for the inputs. The modules works fine with the kernels that come with Ubuntu 10.04, 11.04, 12.04 and 12.10. But, we are supporting a product for every latest Ubuntu versions. So, I need to make it work with the kernel which comes with the distro alone. So I cannot use a custom kernel from kernel.org.

The kernel version is 3.2.11 Why don't you try any other kernel version and see whether you are getting same error or not? I guess, it works.

When I compile the example module I got from LKMPG (hello-5.c) and try to load the driver by passing the module with the following command, it gives the following error: # insmod parameter.ko mystring="bebop" Error: could not insert module parameter.ko: Unknown symbol in module Error in dmesg: [ 3687.132110] parameter: Unknown parameter `mystring' However, if I insert the module without any parameters, it gets inserted just fine. # insmod parameter.ko I am attaching the source code for reference. Kindly let me know what could be done.
