DONAHUE,

Do you use the UUID in grub.conf too ?

Neddy:
to duplicate yes
if grub uses root=/dev/sda2 it will run until / is mounted rw and then crash with the ctrl-d message.
experimental cases:
grub fstab result
dev dev boots
uuid dev boots
uuid uuid kernel panic
dev uuid crash while loading system files

BTW i gave him a drive controller config based on your guide earlier in the thread; what did I miss?

DONAHUE,

Both grub and mount need patches for UUID to work, which is a shame as UUIDs are good for universal USB sticks
I don't think you missed anything.

DONAHUE,

UUID=005ab0ca-f1f8-445c-bced-6a3f3717ebf3 was /dev/sda17 when I started this post. If you recall, I started over from scratch. That meant deleting the partition and creating a new one. A new partition is given a new UUID. That is why they didn't match. The UUID changed. I updated grub and fstab with the new UUID before posting that the results were the same. Sorry for the confusion.

Question related to grub. I am setting grub to point to a config file (grub.conf on /dev/sda16). Should it look like this?

/dev/sda17 is a very trendy partition.
The kernel can only addess as far as sda15. See /usr/src/linux/Documentation/devices.txt

Oh wow! It's working! I'm not sure exactly what fixed it, but I think it was changing to configfile. (hd0,15) worked. Thanks to everyone! You are awesome!

I guess I should explain what I did. My default boot partition is /dev/sda3. This is where the default menu list is. When installing new distros, I've had a lot of trouble with setup overriding my menu list. So what I started doing was running setup to use a new boot partition. In this case, /dev/sda16. After installation completes, I would copy the necessary files over to /dev/sda3 and everything was working beautifully until Gentoo.

I've run into problems before when installing Fedora, and I remembered how someone suggested to let Fedora use its own menu.lst and to tell the default menu list to point to Fedora's menu list by using the configfile command. I figured this would be a good idea for Gentoo as well. Given that Gentoo was setup to believe that /dev/sda16 was the boot menu, there must have been something in the kernel that needed to use /dev/sda16 and not /dev/sda3.

For the most part Jaglover was right. It was just a little more complicated than making sure root=/dev/sda17. Thank you for pointing it out.

I also want to personally thank Neddy and DONAHUE for giving me advice on how to configure my kernel correctly. It was my first time, and I was definitely lost. Thanks a million.

This is the Gentoo entry from menu.lst on /dev/sda3
