[HTC One X] billy.braga:
I was able to build Android using AOSP android-l-preview_r2 project tree + a couple of CM and custom projects (kernel, device, ...). I made it pass the HTC boot animation, and I'm stuck and the android gray logo boot animation.

Here's the part of my logcat that seems to pinpoint the issue and my custom manifest :
