[XenPPC] Question about netbooting with initrd/initramfs

[David M Daly <dmdaly@xxxxxxxxxx>]

I've been having some trouble netbooting
linux on a JS21 with an initramfs, and wanted to see if there were any
known issues, etc. Are there any difficulties in netbooting as an image
on a JS21 with an initramfs/initrd? Any secret voodoo? I'm using Maria's
branch of the linux-ppc kernel both on bare-metal, and on Xen, and I netboot
both. Since I've successfully compiled the Dom0 kernel into Xen, so am
just concerned with the step of getting the initramfs into the linux kernel.


I've followed the instructions straight
from the xensource powerpc wiki for building an initrd. I've also tried
compiling using the specify initramfs source config option in the build
process. I can successfully boot with an initramfs using yaboot, if I specify
an option for it, but I have not successfully booted with an initial image
over netboot, or through yaboot with all the bootargs compiled into the
kernel. 

Any help or pointers are appreciated.

Thanks
