We probably shouldn't have used the word "fail" here. I expect the IO and MSR accesses will always "succeed", but they may not always have the exact effect the OS requested. I think we (the OS) need to get used to this. The HW reserves the right to second guess the OS for a variety of reasons, including temperature, power, reliability, or dependencies between different hardware units that may not be exposed to the OS. I think as hardware becomes more complex and more power-optimized, we'll see more of this, not less. cheers, -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/
