Looking at transaction 367 more closely we see that the kernel was updated to 2.6.32-642.15.1.el6.x86_64 on March 10 but that a number or errors, whose nature I do not comprehend, were also reported.

Reviewing grub.conf I note that the initrd entry is missing from the newest kernel entry. Which of course explains the boot error message. However, as kernel updates are entirely automated when performed by yum I am at a lost to explain its absence.

There is no initramfs-2.6.32-642.15.1.el6.x86_64.img file present in /boot so something is seriously wrong somewhere.
<snip> Fascinating. That's probably what happened to me, that I posted here early in the month, that only way I could get the .15 kernel to boot was to reinstall it.
