[kwlug-disc] Different kernel version on same LTS?

I noticed something odd the other day, a discrepancy of the kernel version
on almost identical machines.
Both machines are running Ubuntu Server 12.04 LTS.

This is a machine that was on 10.04 and then upgraded to 12.04.

$ uname -vr
3.2.0-60-generic #91-Ubuntu SMP Wed Feb 19 03:54:44 UTC 2014

$ dpkg -l | grep linux-im | awk '{print $2}'
linux-image-3.2.0-60-generic
linux-image-server

$ grep DESCR /etc/lsb-release
DISTRIB_DESCRIPTION="Ubuntu 12.04.4 LTS"

This machine was initially the same, but had a hard drive failure, and was
reinstalled on a new drive from a DVD

$ uname -rv
3.11.0-19-generic #33~precise1-Ubuntu SMP Wed Mar 12 21:16:27 UTC 2014

$ dpkg -l | grep linux-im | awk '{print $2}'
linux-image-3.11.0-19-generic

Same distro release as the other machine:
$ grep DESCR /etc/lsb-release
DISTRIB_DESCRIPTION="Ubuntu 12.04.4 LTS"

Note the different kernel version?
The upgraded machine has 3.2, and the installed one has 3.11!

It is not causing any issues. Just curious why this happens.
