*c6-media:" looks like a clue. I'm guessing it's trying a few standard local devices because it can't find the files on the net. Either figure out how to provide the software with the address it needs to load this module, or disable it and see if it can proceed without it.

Edit the file /etc/yum.repos.d/CentOS-Media.repo and make sure that the line enabled = says 0
