Hi all , some time back i have installed FC4 and kernel-devel ( headers) , for building and loading kernel modules. Things were working fine , In recent days , i deleted the kernel-devel ( headers ) by mistake . i tried to install again kernel-devel headers using command "yum install kernel-devel-2.6.11 . it got installed but when i try to build and insert module , It is giving an error "invalid module format" I have verfied in /var/log/messages it is giving a message "disagrees about version of symbol struct_module " when i type uname -r its output is 2.6.11-1.1369_FC4smp. installed kernel-devel directory name is 2.6.11-1.1369_FC4-i686. How i can download the exact kernel-devel headers ? Any pointers will be helpfull.
