It looks like you are using OpenAFS packages built for a specific kernel 
- in this case the 5.5 kernel-2.6.18-194.26.1.el5. My guess would be 
that in updating to 5.6, yum has automatically removed that older kernel.

You need to get kmod-openafs packages that match the version of your 
currently running kernel. Where did you get these packages as they are 
not a part of CentOS?
