Hi Pepedog,
I managed to get my cubox up and running with your rootfs. I did the install to the micro sd before the cubox arrived, but am glad to say it worked right away. I could not get much done with the ubuntu as the console was completely swamped with timing messages (due to lack of a monitor).
Anyhow I would like to compile my own kernel with the video memory reduction built in. I'm not planning to use the cubox fully at present.
I noticed that you have a kernel source in /usr/src. Is it best for me to compile with abs using the linux-cubox 3.4-1 pkg or is there something special about your kernel source?
