We keep the last three kernels installed as a matter of policy and
the oldest of these on the development box is
kernel-2.6.18-194.32.1.el5. I do not plan on booting into an older
kernel on this host. Therefore, I will work from the assumption that
this issue is not going to cause us any difficulty and will
disappear on its own with the next kernel update.
Thank you.
