This is mostly harmless.. since the MCG_CAP space is shared and has no conflict between vendors. Also just the CAP being set has no effect. The Guest OS needs to opt-in and the SIGBUS indicating SRAR are the only ones that are treated special treatment. Also Intel was the only one broadcasting MCE's.. so we are like the rest now :-) Cheers, Ashok -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
