[coreboot] Native ram init panics linux kernel on samsung lumpy with CELERON 867 cpu.

[Persmule]

Hi all,

Recently I bought a second hand samsung lumpy
(https://www.chromium.org/chromium-os/developer-information-for-chrome-os-devices/samsung-sandy-bridge)
with CELERON 867 cpu, and tried to build a coreboot image with seabios
in order to use this chromebook as an ordinary PC laptop running GNU/Linux.

It seems that native ram init works on lumpies with core i5 cpu, but on
mine, coreboot built with native ram init can run payloads with no
problem, but linux kernel will panic with outputs showed on the attached
photo (related to processors' synchronization?). Now I have to use Intel
FSP to perform ram init, on which linux
kernel (and GNU/Linux) works fine.

Config files for FSP and native ram init are also attached.

Best regards.
