I'm not following this problem description, can you rephrase ? Is it a timing problem between the driving starting (as the built in) and it triggering a firmware load (that fails due to the rootfs not being ready) ? presumably the i915 was built in for a reason, i.e. so it is available in early boot without the need to load a module. And this change would break that functionality. Also, are there any other build settings that need to arrange for the module autoload ? Since there is that possibility, restating the problem you are trying to fix would be good. Bruce
