What is the kernel module you are trying to load? Show exact command you used.
What is your LInux distro/kernel version?
What is the relevant hardware (if any)?
The kernel module I am trying to load is a custom module... namely video_server.ko. The kernel being used is 2.6.24-24-rt. I do the following
sudo ifdown eth0 2>/dev/null || true
sudo ifdown tt100 2>/dev/null || true
sudo rmmod r8169 2>/dev/null || true
sudo rmmod video_server 2>/dev/null || true
sudo insmod /home/demo/video_server.ko
sudo modprobe r8169
sudo ifup bg0
sudo ifup tt100
sudo ifup eth1
i get the error after the font in red
Is that kernel module supposed to work with a specific piece of hardware?
Did you encounter any errors/warnings when you compiled the module?
Hi..
Yeah it is supposed to work with a specific piece of hardware (realtek NIC). I did not encounter any errors or warning while I compile the module.
Is there documentation that comes with the code that would suggest compatible NICs? Perhaps only certain RealTek cards are supported? Is there a debug switch you can give to the module when you load it?
I am basically working in a research project and a company has given us a system , which I want to mimic into my own system. They use 8.04 ubunutu and 2.6.24-24-rt kernel. I have the same in my system and the same goes with the NIC card. I cannot give a detailed explanation because, there are lots of codes given by the company each linked for which even we do not have a full understanding. So I am not able to understand if NIC and kernels are same..why can I not load it. i want to know the reason for the error so that I can retrace things and go back and change something in the code if I need to.
You might want to visit kmuto.jp/debian/hcl/ and paste the output from lspci -n into the big box. You will get more details about your hardware and what the expected kernel module is. Sanity check ....
