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.
