I tried building the kernel using the SDK vm, but I'm not sure why it won't boot. I used the quark.cfg from the BSP and added all the netfilter, iptables and xtables stuff to the kernel. Am I on the right track? Do you have the .config file you use posted anywhere?
I don't have serial right now, so I can't see what it's outputting... gear is on the way.
Thanks
