Has anyone successfully booted into gentoo using the arm64 gentoo-sources kernel either configuring manually in menuconfig or using genkernel all?  


I've confirmed I have a good u-boot image on my SD card, but upon boot, its falling back to my "stock" ubuntu install on the internal mmc.

My assumption is that I'm missing something I need in my boot partition on the SD card.  So far, I've tried with a genkernel generated image.  Haven't braved manually building a kernel yet.


Here's the TTL output.  Note it appears to look for a kernel on the SD but doesn't like what it sees:
