Chris,
Check your /etc/grub.conf file and make sure your default is set to the correct and current kernel image. (default 0 ) should be the latest.
2.6.9-42.0.3.ELsmp
After its set right, reboot the server and the new kernel should be active. It sounds like the new kernel was installed but wasn't put as first the grub boot loader or you ddin't reboot the machien after the update.

Can anyone offer any advice on troubleshooting/resolving kernel updates that fail to boot where I do not have KVM access and have a lackadaisical provider?
My current kernel is 2.6.18-53.el5PAE #1 SMP Mon Nov 12 02:55:09 EST 2007 i686 i686 i386 GNU/Linux running on CENTOS Enterprise 5.2 i686 on standard with the following hardware...
Intel Core2 Quad Q6600, 4gb RAM, 3Ware card running RAID 1
If I run yum update, the current update comes up as kernel-PAE-2.6.18-92.1.6.el5 and after running echo "savedefault --default=1 --once" | grub --batch followed by reboot, it falls back to the original kernel.
Running excludes until I come to no update available gives me the same results, i.e....
yum --exclude=kernel-PAE-2.6.18-92.1.6.el5 update
yum --exclude=kernel-PAE-2.6.18-92.1.6.el5 --exclude=kernel-PAE-2.6.18-92.1.1.el5 update
yum --exclude=kernel-PAE-2.6.18-92.1.6.el5 --exclude=kernel-PAE-2.6.18-92.1.1.el5 --exclude=kernel-PAE-2.6.18-92.el5 update
In other words, not even kernel-PAE-2.6.18-92.el5 will boot.
There are no kernel excludes in my yum.conf and nothing is written to /var/log/messages concerning the kernel reboots that fail.
Any advice is gratefully received.

i believe kernel-smp-2.6.9-42.EL.i686.rpm is for dual processor centos 4.3 compatible

Hello layer0,
Is it possible to upgrade kernel using yum and trigger the other and do same commands ? In case, I have more than 2 servers.
