newbie question: up2date kernel & install Cd stop working

Our company is running Red Hat Enterprise Linux ES v4 which was preinstalled on a Dell Xeon dual core server. Through the up2date we updated the kernel packages which are nornally set to ignore.

After updating and rebooting the server no longer recognizes the installation cds. For example if I try add a application through add/remove application it asks for CD # but will continue asking for it after I insert it. Before I did the kernel update it didn't have this problem.

The only thing I changed was up2date the kernel packages and particition a hard drive. I removed the hard drive partition to try to get this to work but without sucess.

Would updating the kernel cause this? do I need to download updated cds or can I undo the kernel update?

Thanks for your help.

It seems that the system-config-packages appliction (the add/remove programs) may be broken;

You are free to download the source for system-config-packages extract and apply the patch (see the first link) to see if this fixes the problem.

Yes it is possible to undo the kernel update, but this is not advisable since the updated kernel fixes a number of issues. Do a quick check and see if you have the older kernel still available for booting;

rpm -qa 'kernel*'

If you see more then one kernel (version number wise) then you can simply edit the /boot/grub/grub.conf file to boot the system to the older kernel. If not then install the older kernel from the installation media (by hand from the mounted media) or from RHN. To install the older kernel kernel as root from the console or xterm session type something like;

rpm -ivh kernel-<version-number-here>*.rpm --oldpackage

This should install the older kernel keeping the new kernel installed, this way you can choose which kernel to boot the system(s). Please install the same type of kernel that is currenty running, hint: uname -a
