Joseph,

I did all of that, although I used mkinitrd rather than
/sbin/new-kernel-pkg.
 I've had to rebuild the kernel several times, first to apply the patch to
stop the fans from running at full speed, and then to enable Fibre Channel
and LVM
support, I'm getting quite comfortable with the process now. That all
worked perfectly for 2.6.8.

I can build a kernel for 2.6.10 which works too, but when I add support for
the Fibre Channel
it just won't boot. It gets to the point in the boot process where it would
detect the Fibre Channel
disks and just stops. The same thing happened when I tried 2.6.9.

I seem to have solved my particular problem now however. I took the 2.6.8.1
source from
www.kernel.org and patched in the tree below fs/ as well as
include/linux/fs.h into the YDL
2.6.8 and that built quite happily. The problem I had with NFS seems to
have gone.

There just seem to be something in 2.6.9 and 2.6.10 that stops the kernel
from finding
the Fibre Channel disks.

When you rebuilt the kernel, what did you do to install the new kernel?
maybe there's an issue there.

When I rebuild a kernel, it has a new name, for example

      vmlinux-2.6.10-2

Take a look at

      path-to-kernel-source/include/linux/version.h

to determine the name of your new kernel.

* install kernel and system map

      vmlinux -> /boot/vmlinux-2.6.10-2
        System.map -> /boot/System.map-2.6.10-2

* install modules

      make modules_install

* generate a new /boot/initrd file

      /sbin/new-kernel-pkg --rminitrd --rmmoddep --remove 2.6.10-2
      /sbin/new-kernel-pkg --mkinitrd --depmod --install 2.6.10-2

* edit /etc/yaboot.conf
Add an entry for the new kernel:

      image=/boot/vmlinux-2.6.10-2
        label=linux
        read-only
        initrd=/boot/initrd-2.6.10-2.img
        root=/dev/sdb4
        append="rhgb quiet"

* install the yaboot boot loader to the bootstrap partition:
RUN:
       /sbin/ybin -v         [-v to see what it's doing]

-Joseph
