apart aTc's long-forgotten -next project, there's no effort to update 
the whole Pandora OS inc. the kernel.
And there's a lack of communication about your kernel for OP, I mean if 
you or ED or notaz post a pinned thread, it will add a lot of 
Some questions :
Does your kernel needs u-boot to be updated ?
Does it run the command line ?
Does it "run" X ?
What is known to be broken ?
