The mainline kernel works beautifully, thanks! :-)
Now the only question is how does it coexist with the regular kernels?
More precisely, when I do a "yum update", and there are new kernels
available in the update, how will they be ordered
in /boot/grub/grub.conf, and which one will be the default on a
subsequent boot?
I have enabled the elrepo-kernel repository, so both types of kernels
will get updates. However, I want to boot only from the mainline
kernels, never from the regular ones. How should I configure grub
and/or yum, to make this stick?
Thanks again for the advice! :-)
Best, :-)
Marko
