surprised I have not seen anyone mention the other two things which can conspire to cause reboot trouble (with the kernel) with long uptimes
- automatic updates by yum-updatesd
- small (only 3) installonly_limit
If you are not careful, the last known working kernel is gone when you go to reboot. :(
My reboot times are regular, (still on F12 on this machine) but I always copy the kernel files into a subdir 'tmp-backups' so I can get them back if needed, even if yum deletes them.

I usually am mindful of both of these settings.
