[Samsung Galaxy Tab S3 ROMs, Kernels, Recoveries, &] ianmacd:
I've been silently trying to get this going over the last few week, but something is fundamentally wrong here.

Any kernel I build and wrap in your modified boot.img for the T820 fails to boot. More accurately, the device doesn't even get past the bootloader.

I've copied off last_kmsg after rebooting to recovery, but as far as I can see, there's nothing in there from the previous boot; precisely because the device never got further than the bootloader! I include it here anyway on the off-chance that I'm failing to notice something of relevance.

This is confusing. I frequently build and install kernels for my S9+, so I'm not a complete (only a partial) nincompoop in this area. Admittedly, I'm usually using sources that someone else has already refined and previously built for the device. In the case of my T820, I downloaded the source myself from Samsung's site, and I can't help but feel that it needs some massaging before it can be run outside of Samsung's internal build environment. It builds fine. It just won't boot. It doesn't build a DTB, but you said the one from your boot.img ought to be close enough.

I suspect that if a seasoned Android kernel hacker were looking over my shoulder, we'd have this thing booting within an hour. I'm convinced I'm missing something fundamental here, since the kernel doesn't even get bootstrapped.

Here is the last_kmsg:
