Hi,

os: debian on an ibook(G4, 1G, 12")

I've just installed a new kernel image (kernel-image-2.6.11-powerpc)
with initrd support, but was unable to boot the new kernel, which stops
at:

   Please append a correct "root=" boot option
   Kernel panic - not syncing: VFS: Unable to mount root fs on
   unknown-block..

In `/' i have:

   /initrd.img -> boot/initrd.img-2.6.11-powerpc
   /vmlinux -> boot/vmlinux-2.6.11-powerpc
   /vmlinux.old -> boot/vmlinux-2.6.9

and in `yaboot.conf':

=====================================
boot=/dev/hdc2
device=/[EMAIL PROTECTED]/[EMAIL PROTECTED]/[EMAIL PROTECTED]:
partition=4
root=/dev/hdc4
timeout=30
install=/usr/lib/yaboot/yaboot
magicboot=/usr/lib/yaboot/ofboot
defaultos=linux
default=debian

image=/vmlinux.old
        label=debian
        read-only

image=/vmlinux
        lable=debiannew
        root=/dev/hdc4
        initrd=/initrd.img
=====================================

As directed, i tried to append various root= options, still failed. To
boot my old kernel, on the second stage of yaboot type either
`/vmlinux.old' or `/vmlinux.old root=/dev/hdc4' is fine; while, to boot
the new 2.6.11 kernel, root=/dev/hdc4, /dev/hda4, hd:4,
/[EMAIL PROTECTED]/[EMAIL PROTECTED]/[EMAIL PROTECTED]:4, ... won't work.

I'm kind of confused with it, any ideas?

btw, 2.6.9 is built by hand myself.
