Murphy's law. Now that I'm trying to debug, I can't reproduce the problem any more.

Non debug:

startup.nsh> elilo xen
ELILO
Loading xen.....done
Loading initrd xenlinux...initrd.c(line 90):read initrd(xenlinux) failed: 1

ELILO boot: xen
Loading xen...ConvertPages: Incompatible memory types
plain_loader.c(line 292):relocation is disabled, cannot load kernel
Exit status code: Load Error

Debug output is also attached.

One thing I noticed is that if the loading of initrd (xenlinux) fails, the memory for initrd is freed, but the memory for the main image (xen) is not freed?
