I've been trying to find a problem in linux that makes it not boot when used as the payload in the KGPE-D16. The symptom is that I get no output at all on serial when linux starts.
I finally got it down to 1 commit today in linux.
commit 974f221c84b05b1dc2f5ea50dc16d2a9d1e95eda
Date: Thu Apr 28 17:09:04 2016 -0700
x86/boot: Move compressed kernel to the end of the decompression buffer
If I build a linux kernel up to but not including this commit, all is well. If I build with this commit, Linux is silent -- no serial output.
Anyway, I will be looking at this, but if you have solved it let me know.
thanks
ron
