Most likely. > also i don't understand why /proc/meminfo only reports 1GB... I would compare the e820 maps between single and dual core. Perhaps the initrd happens to be loaded somewhere where it overwrite other memory. Another reason could be broken MTRRs not covering all memory correctly. This can cause strange mmeory corruptions Also if single core is an old stepping memory remapping might work differently. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
