yum - problem installing kernel

[Barry K. Myrvold]

Any help would be appreciated:
I have not been able to install new kernels.  When I run yum update, all 
new packages from the various repositories install  successfully, except 
yum has been stalling on the installation of updated kernels. 
For example, I recently ran 'yum update' but it stalled while installing 
kernel-smp-2.6.16-1.2122_FC5.  After a while I gave up and hit Crl-C 
shutting yum down.
I then downloaded the rpm and attempted to install it to the same effect 
- it stalled at some point during the installation process.  I hit 
Ctrl-C and got the following mesage:
error: %post(kernel-smp-2.6.16-1.2122_FC5.i686) scriptlet failed, signal 2

Now, the computer can't decided whether that kernel is installed or not 
- see below:
 [barry at localhost Desktop]$ sudo rpm -ivh 
kernel-smp-2.6.16-1.2122_FC5.i686.rpm
Preparing...                ###########################################

        package kernel-smp-2.6.16-1.2122_FC5 is already installed
[barry at localhost Desktop]$ sudo rpm -e kernel-smp-2.6.16-1.2122_FC5.i686.rpm
error: package kernel-smp-2.6.16-1.2122_FC5.i686.rpm is not installed

Here's rpm -q kernel-smp:
kernel-smp-2.6.15-1.2054_FC5
kernel-smp-2.6.16-1.2111_FC5
kernel-smp-2.6.16-1.2122_FC5

and grub.conf looks like this  (no 2122 kernel!):
