installing kernal source...
Just make sure you have your kernel sources installed. You can use Yast2 to get and install them. Also, make sure they are linked to /usr/src/linux. If they are not, just link them:
* ln -s /usr/src/linux-kernel-2.X.X /usr/src/linux
If a symbolic link already exists, but you are sure it's not your kernels, just erase it before making the new one.
* rm /usr/src/linux
how do i use yast to install kernal source
