[coreboot] Coreboot / Libreboot on KGPE-D16 restarting / turning off randomly

[Piotr Kubaj]

I'm trying to flash the latest Libreboot images on KGPE-D16. I'm using 2 
6262HE CPU's and 56GB RAM (3*16GB + 4*2GB).

The 2GB RAM's are from Micron and they cause the system to go in the 
reboot loop even before graphics are initialized (there's nothing on the 
screen, I only get serial output).

But I don't care that much about those Microns, I only have 8GB from 
them. What matters to me more is the rest (3*16GB RAM). Those are 2 
KVR16R11D4/16 and 1 KVR16R11D4/16HB. KVR16R11D4/16 are specifically 
recommended by https://www.coreboot.org/Board:asus/kgpe-d16. Even then, 
with those 2 KVR16R11D4/16 put in the RAM slots that work with vendor 
BIOS just fine (the latest 3309 version), the system using Coreboot / 
Libreboot reboots randomly, usually during booting the OS (I use FreeBSD 
11.0-RELEASE). There's nothing on the serial console and seems to just 
reboot randomly.

The system uses pure Libreboot config with added nvramcui and memtest 
payloads and SeaBIOS as a primary payload. Since I use 16MB chip, I 
compiled my own image for it.

Any ideas about this? I spent yesterday about 8hrs trying to make it 
work and am currently out of ideas.
