The symptoms you describe could be a side effect of being previously hit by http://bugs.centos.org/view.php?id=2914 and https://bugzilla.redhat.com/show_bug.cgi?id=447841.
Those bug items describe workarounds. After you get mkinitrd upgraded to that in 5.3 the problem should go away, although you may have to manually fix up the results of the bad kernel install.

Thanks for the belated info, anyway. But this doesn't seem to apply here. No crypto fs and no problem with mkinitrd at all. It didn't happen with all the earlier updates, just this one, and there was no indication during the install that there was a problem. I just noticed it before reboot because I have to adjust the xen kernel line after each kernel upgrade.
