[Techtalk] Gentoo Kernel Upgrade - unable to mount root partition

Hi everyone,

I've had a few crazy months where keeping my box up to date has been
really low on the list of priorities. Today I finally got around to
upgrading my kernel from 2.6.20 to 2.6.22.

When I try to boot into the new kernel, I get the error message:
Root-NFS: No NFS server available, giving up.
VFS: unable to mount root fs via NFS, trying floppy

My root partition is on /dev/sda5

By changing root=/dev/sda5 to root=0305 in the grub.conf file, I was
able to get past that point in the boot process, but then I got
complaints that fstab doesn't define /dev/hda5... which is because
I've got that down as /dev/sda5.

I don't dare edit the fstab to reflect the hda thing, since I'm pretty
sure I won't be able to boot into this (2.6.20) kernel if I do.

Any idea what sort of changes I should try in the menuconfig?

Any other things I can look at to figure out what exactly is causing this?

Kind regards,
