I hate to bring up old topics - but I'm still experiencing this problem. I'd held off asking about it - hoping further fixes would correct it, but no luck.
<br />
<br />One of our machines is a Centos based 5106R. It won't boot unless I select the oldest kernel in the boot splash screen -> 2.6.18-308.11.1.el5. If I allow it to try the latest 2.6.18-371.6.1.el5, I get a kernel panic and lock up.
<br />
<br />I tried Jason's fix down below. No luck.
<br />
<br />Then I tried Michael's script. At first, I received complaints about "-V" not a valid option for sort. Thought he might be trying to do a unique sort, so changed the -V to -u and ran it again. Still no luck.
<br />
<br />So the machine won't reboot on its own. I've got to manually select the oldest kernel to get it to boot.
<br />
<br />Anyone know a fix for this issue? This isn't the Scientific Linux most people with this problem was running - this is Centos. So I'm at a loss, but need to fix it.
<br />

I actually ran into you issue with a recently-deployed 5108R - sounds like I

should have been surprised since it should have been cleared up in that

release. At any rate, I made the symlink you did and ran this script to

peruse my boot folder and build a proper grub.conf.
