Some people in this list may be confusing, so let me summarize my boot
problem.
I am using JS20 (884241X) to run XenPPC, which is booted from local disk
through the /etc/yaboot.conf like this.
# header section
partition = 2
timeout = 600
default = xen
# image section
image = /boot/vmlinux
label = linux
root = /dev/hda3
append = " quiet sysrq=1 insmod=sym53c8xx insmod=ipr"
initrd = /boot/initrd
# kawatiya 2006/08/24
image = /boot/xen-3.0-unstable
label = xen
append = "xen -- root=/dev/hda3 sysrq=1 insmod=sym53c8xx
insmod=ipr"
However, I have several boot problems with recent versions.
1. I could not boot our internal version which is a little bit old version,
but contains the SMP patch.
It failed like this.

I know this is caused by the SMP patch.
2. When I reverted xen/arch/powerpc/setup.c to non-SMP version, I
encountered another problem.

Root-NFS: No NFS server available, giving up.
VFS: Unable to mount root fs via NFS, trying floppy.
VFS: Cannot open root device "<NULL>" or unknown-block(2,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(2,0)
<0>Rebooting in 180 seconds..
It seems that boot parameters (root=/dev/hda3) is not passed to dom0
Linux.
3. I also cannot boot the official XenPPC in XenSource, which I already
reported.
:
Welcome to yaboot version 10.1.14-r716.SuSE
booted from '/ht/ata@4,1/disk@0'
Enter "help" to get some basic usage information
boot: xen
Please wait, loading kernel...
Can't find a loadable segment !
boot:
I think this is related to the boot wrapper removal.
