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.
Just to clarify, the raminit blob for samsung/lumpy is not technically Intel FSP, but different (MRC) blob created at Google.
Config files for FSP and native ram init are also attached.
Please send output of cbmem -c and inteltool -a once system has booted with raminit blob.
Best regards.
