I've had cased where a kernel didn't work as expected though, but we don't reboot a server every 2 months to see if the kernel might have failed.
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.
