All, we're seeing recurring but intermittent failures in osstest on just the two hosts using these particular CPU types. The closest similar ones, using Xeon E5-2407 v2, do not exhibit this same behavior. We do note that the latter run at microcode level 0x427, while the problem ones are only at 0x416, and IanC is in the process of trying to integrate microcode updates with osstest. However, since there doesn't seem to be any matching erratum documented of these CPU models, we aren't really assuming that a microcode update (0x428 appears to be the newest available) would help here, and hence we'd like to ask for your assistance in possible further diagnostic steps, or suggestions towards a resolution.
