Hello,
I have just installed CentOS 7 onto two servers and applied all the current patches. There are currently two kernels installed:
# rpm -q kernel kernel-3.10.0-123.el7.x86_64 kernel-3.10.0-123.9.3.el7.x86_64
However, if I reboot the servers they both start up on the older kernel:
# uname -r 3.10.0-123.el7.x86_64
I would have expected them to restart using kernel 3.10.0-123.9.3. I know I can manually select the kernel to use at boot time (from the grub2 menu), but, as with CentOS 6, I would have expected the servers to reboot using the latest kernel automatically.
Has anyone else noticed this? Any ideas as to why it might be happening?
Thanks,
John.

/etc/sysconfig/kernel
Yes and no. The above file has not been changed and states that a new kernel should be the default.
It seems this problem has already been reported as a bug to CentOS and up to RedHat: https://bugs.centos.org/view.php?id=7651

Someone already pointed you to the upstream bug for this.
Uninstalling the original release kernel (3.10.0-123.el7.x86_64) should provide a workaround as the rest of the kernels should then be sorted in the correct order.
