Hi JJ. Glad you got to shutdown completely using the earlier kernel. You have 
obviously done a yum update, and a newer kernel was installed. If you are 
using yum for updates, and want to keep the kernel that is shutting down ok, 
you need the edit something. Yum as default only keeps 2 kernels, so if you 
run yum update again, and there is a yet newer kernel, it will install that, 
and remove the oldest one, which in your case is the one you want to keep.

You can change this behaviour by either disabling the plugin, or changing the 
number of kernels to save.

Open the CLI, and su to root, open a text editor, go 
to /etc/yum/pluginconf.d/installonlyn.conf.

My FC6 one looks like this.

[main]
enabled=0
# this sets the number of package versions which are kept
tokeep=2

I just disable the plugin by just changing "enabled=1 to enabled=0", but you 
can just change the "tokeep=2" to whatever number you like. 5 might be a good 
number. It's possible that the next kernel update from the one that's not 
shutting down completely will again shutdown completely, but you can't be 
sure, so you want to keep the 2.6.18 one which is doing what you want.

After saving the changes, keep the text editor open, and go 
to /boot/grub/grub.conf .  Afew lines down you'll see this.

#boot=/dev/hda
default=3
timeout=30
splashimage=(hd1,0)/boot/grub/splash.xpm.gz
title Fedora Core (2.6.10-2.3.legacy_FC2)

I say this, but this is from FC2. The "default" line sets the kernel you want 
to boot. Grub starts at "0", so you can change this to "1", then at the 
moment it will boot the 2.6.18 kernel that works ok. The "timeout" line I 
have already changed. The default is 5 secs, and it's worth changing this to 
30, as it gives you a bit more time to make decisions as to which kernel you 
want to boot. The next line "splashimage" IIRC is "hiddenimage" on FC5, and 
FC6. if you are not seeing the grub menu when you bootup, you can put a "#" 
at the start of this line (no double quotes), which will comment out the 
line.

Just a few suggestions, so you don't lose your working kernel, along with the 
grub stuff.

Nigel.

Btw. I use apt, and synaptic as update managers, so am not involved in this 
ptential kernel problem with yum.
