I think the first step is to fix the problem that prevents current kernels from booting. It's not really practical to debug v4.4. It sounds like the firmware fails to even load v4.11? If that's the case, it's probably not a problem with the kernel itself, since it hasn't even started executing. Possibly a kernel size problem? Maybe the v4.11 kernel is larger than v4.4, v4.9, etc? Does v4.11 boot if you strip out non-essential drivers? > (1) http://www.downthebunker.com/reloaded/space/viewtopic.php?f=79&p=2755
