Hello,
I am totally new to Usenet :-) so don't be angry for me :-)
I have a problem with my gentoo, I mean, J have a problem with
kernel 2.6.7-r6 (gentoo dev sources). I' ve configured it as usual,
compiled, copied to /boot (I' ve made two options in GRUB to boot new and
old kernel) and I receive a error message during initialization :
"can't mount root device, check "root" option in your GRUB"
(it's not exactly like that but I don't remember)
What's wrong ?

Post the backup copy of your previous working grub.conf, and your new
grub.conf so we can take a look.

Check your grub.conf to make sure it's pointing to your boot partition,
and try reinstalling grub.

Remember that when using grub the first harddrive is 0 and THE FIRST
PARTITION is also 0. Eg. hd(0,0). Check so you havn't made the most
common misstake with grub naming the partition as you're use to when
writing /dev/hda#

Here is my grub file:

title=Gentoo Linux 2.6 kernel
root (hd0,2)
kernel (hd0,2)/boot/2.6.5-gentoo-r1-4 root=/dev/hda6

The first root is the /boot partition, the "root=/dev/hda6" is the /
partition.

It's possible that you forgot to include your filesystem drivers into
kernel.
Check if you are using filesystem support (ext2, ext3, reiserfs)
statically. Do not use modules for filesystem.

If the drivers ARE present within the kernel it is also possible that
entries within your /etc/fstab file are not properly specified.

He's having problems with his root device, which means he can't even see the
partition which /etc/ is on. It doesn't sound like an fstab problem to me.

Definately sounds like a filesystem kernel support or grub.conf problem.

Try adding root=/dev/hdxx to the kernel line in the grub.conf file.
Substitute the actual partition of your root for hdxx.
Look at the grub.conf.sample file for examples.

If that doesn't work, try doing the same in /etc/fstab (you will need to
manually mount your root partition in run level 1). This worked for me.
