Having a simple shell with ping and wget/curl is a real help here. >> If you can provide me with a link to your vmlinux and rootfs with >> busybox or similar in it, I can take a look to see what is happening >> here.

I also have a VPS with scp access that I could temporarily grant you access via an SSH public key if that helps? ATB, Mark.
