Do you have any excludes in /etc/yum.conf? We had an issue about a year
ago, where, in spite of exclude kernel, someone other than me ran an
update, or there was some auto-update, I don't remember, and it appeared
to *partly* install the kernel... and did not appear to do any
post-install actions (like building the ramdisk). I reinstalled the
kernel, with my usual disableexcludes=all, and the upgrade succeeded, and
all was good.
