<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hi Srinivas,<br>
<br>
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.<br>
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.
<br>
So I cannot use a custom kernel from kernel.org.<br>

<div>Why don't you try any other kernel version and see whether you are getting same error or not? I guess, it works.</div>

Hi all,<br>
<br>
I use the kernel version "3.10.0-4" that came with Ubuntu distribution.<br>
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:<br>
<br>
# insmod parameter.ko mystring="bebop"<br>
Error: could not insert module parameter.ko: Unknown symbol in module<br>
<br>
Error in dmesg:<br>
<br>
[ 3687.132110] parameter: Unknown parameter `mystring'<br>
<br>
However, if I insert the module without any parameters, it gets inserted just fine.<br>
<br>
# insmod parameter.ko<br>
<br>
I am attaching the source code for reference. Kindly let me know what could be done.<br>
<br>
Thanks,<br>
Binoy<br>
