Ok, but noone talk about the first problem.

What is wrong is that
rpm -ivh kernel-2.6.16-1.2111_FC5.x86_64.rpm
kernel-devel-2.6.16-1.2111_FC5.x86_64.rpm

        package kernel-2.6.16-1.2111_FC5 is already installed

and 

rpm -e kernel-2.6.16-1.2111_FC5.x86_64.rpm
kernel-devel-2.6.16-1.2111_FC5.x86_64.rpm

error: package kernel-devel-2.6.16-1.2111_FC5.x86_64.rpm is not installed

no solution about that?
I think is not a problem related to disk spaces because yum check for
space requirement.

Maybe a rpm database's corruption.
I can try with --force but I want to check other way before.
