Rollback Kernel?

Hi all,

I've been using FC3 with the default kernal installed on the CD, which I believe is 2.6.9. Anyways all was well and I was enjoying my linux experience until I decided to update to the 2.6.10 kernal via RHN up2date. After the reboot and getting into the new kernel nothing works and everything is haywire. My network configurations are not working, my sound is all messsed up, lost support for NTFS, etc etc.

When i reboot and choose the original kernal from grub, everything is fine again. Is there anyway I can rollback the installation of the 2.6.10 kernal so that I can go back to the way things used to be. Right now even when I'm in 2.6.9, the up2date critical warning thing tells me that newest kernel installed is 2.6.10 and I should reboot to it. I don't want this

you just want to boot the old one by default? just edit either /etc/lilo.conf or /boot/grub/grub.conf depending on the bootloader you use, and either change the default entry, or move your entry of choice up the list.

as far as up2date goes... no idea... never used it.

All you have to do is remove the new kernel which is pretty easy via rpm.

First, find the exact name of the kernel you want to remove with the command:
rpm -qa | grep kernel
This will list all packages installed with the name kernel. Find the one in the list that you don't like then remove it with:
rpm -ev kernel-version
The kernel should be gone and will not appear in your bootloader menu.

However, I recommend keeping up to date with latest kernels. Sometimes when you update kernels, you have to reconfigure somethings. For example, I can tell you right away that in order to get ntfs support back, go to and look for the rpm specific to the kernel version and install it. I do that ever time there's a kernel update.

As far as your network and sound goes, did you have to do something after you initially installed FC to get them working? You may have to do it again.

Just some suggestions...
