One observation and question: 1. I can build core-image-minimal/sato with meta-dl (with github 3.8 or yocto-3.8 kernel) with yocto on "danny-8.0" tag 2. I cannot build a successfully bootable core-image-minimal (with meta-dl) with yocto on "1.4_M4" tag, the image was stuck during booting..
My build machine is Ubuntu 12.04 LTS. Before I debug more, I want to check with you to see if there is any thing that you can think of. Since I am planning to move to the yocto's master, so that I can pick up "linux-yocto_3.8.bb".
