Going back to a kernel version

Hi everyone!

I'd like to know how can I go back to a previous kernel version. Downloading it and installing it using rpm is fine? All dependecies are satisfied? And what about the packages I've previously installed? If the kernels are 2.6.x, anyproblem?

Thank you.

With using a kernel rpm, if you installed it with the rpm -i switch, not the -U switch it "should" leave your old kernel intact and you can select at your grub/lilo boot prompt. You'll need to satisfy any dependencies yourself. Packages may experience problems with the new kernel but probably shouldn't if they are new'ish. Check the documentation for the kernel and the packages and see if they discuss any compatiblilty problems. Have a look around on google, that sort of stuff.

Make sure you backup before doing any sort of kernel work!!!!!!

basically linux keeps a consistent set of kernel headers in /usr/include
that were the ones used to compile glibc.
so the interface stays the same and you can use any kernel you want no problem.
this can possibly get a little strange in certain special cases involving kernel hardware drivers
and their user level interfaces but generally it's ok.
you also of course will have to reinstall any special driver for the new kernel

Hmmm... that's great! I could reboot the other kernel version kept in the system. I just had to edit the /boot/grub/grub.conf stuff. Seems some pckg dependencies problems happen. I'll check other references to try to solve'em all.

Thank you for your responses, guys!
