- Use the full mask described by the erratum as with a sufficiently high number of these false-positives, the overflow bit (bit 62) additionally gets set [7]. - HSD131 has been brought into several other Haswell-derived CPUs including to the next generation, i. e. Intel Broadwell. Thus, also skip reporting of these benign errors by default on CPU models affected by HSM142, HSW131 and BDM48 [2 - 5], describing the HSD131 silicon bug for additional models. Also, Celeron 2955U with a CPU ID of 0x45 have been reported to be covered by this fault [6], with the specification update concerned with HSM142 [2] only referring to 0x3c and 0x46.
