(I use the same procedure successfully on x86_64 and itanium2 servers). The relevent silo section looks like this: image=/boot/2.6.20.image label=2.6.20 initrd=/boot/2.6.20.initramfs partition=2 read-only The kernel loads and boots and I see Allocated 8 Megs of memory at 0x40000000 for kernel Loaded kernel version 2.6.20 Loading initial ramdisk (127932430 bytes at 0x1000000 phys, 0x40C00000 virt)... / Remapping the kernel... done.

I haven't tried this (initramfs) with earlier kernels, so I don't know whether this is a regression. Any clues about how to solve this would be greatly appreciated.
