[coreboot] Coreboot computer doesn't boot with 2 CPU

[d.verdi]

Hi to all,
I had this problem: when I start the computer with 1 cpu (opteron 6282se) everything is fine, if I add the second CPU, the computer doesn't boot, did you have any suggestions? I put only 2 rams module, following the Asus kgpe d16 manual, is that the correct order (one in the first and one in the last orange socket)?

Thank you very much
Dave
