This means CPUID.ARAT is set for the new board, and not set for the old board. You can observe that also in /proc/cpuinfo flags where you will likely also find a visible stepping difference between these two boards. Bring-up Avoton had ARAT disabled, and also had broken deep C-states. It looks like that is what your old board has. Throw it away and use only production steppings. If you are stuck w/ pre-production hardware, then you need to manually modify upstream Linux to make it happy -- since upstream Linux only cares about production hardware. thanks, -Len -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
