surprised I have not seen anyone mention the other two things which can conspire to cause reboot
trouble (with the kernel) with long uptimes
1) automatic updates by yum-updatesd
2) small (only 3) installonly_limit

If you are not careful, the last known working kernel is gone when you go to reboot. :(

I usually am mindful of both of these settings.
