Does anyone what the difference between making a kernel with "make zImage" and "Make zImage.initrd"? - Apart from the obvious fact that the later builds a kernel which expects the rootfs to be on the RAM disk.
Anyway, the problem I'm having is that with the "make zImage" kernel, I get alot further in the boot sequence. Here is my output: loaded at: 00200000 0020B1E4 relocated to: 00600000 0060B1E4 board data at: 00600190 006001B8 relocated to: 001F0100 001F0128 zimage at: 00206000 00275065 avail ram: 0060B1E4 02000000 Linux/PPC load: root=/dev/nfs rw Uncompressing Linux...done.
