Yes, I'm still building version with 3.14 kernel. I'm little behind with everything - it is uploaded now to usual folder.
This black screen issue happen only to some users. Others prefer more modern kernel. That's why this decision was made. And imx6 project doesn't have such support as others that's why this issues remain. Sorry for that. I'm only keeping all the pieces together.
Everything is already available to build this images manually (I don't hold anything back). The only missing part for LE7/8 in repository is libcec patch. But this was already fixed for LE9.
