RE: [XenPPC] Question about netbooting with initrd/initramfs

David,

 

Could you provide a little more info-- error messages, build command line.

 

You have confirmed that the init ramdisk itself is no corrupt through yaboot, correct?

Subject: [XenPPC] Question about netbooting with initrd/initramfs

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
