Then help me understand, I test 10 Transmeta chips, and find all of them start miscalculating branches when some unit is heated with some odd instruction sequence. Should I add Transmeta to the whitelist? I would say no, but it sounds like you're saying, that means nothing.
After testing 1k chips, if all 1k failed under load, I would say we need to insist on a more specific cpuid whitelist, maybe consider design changes, and get feedback from the vendor? I really think this is pretty reasonable.

If 1k out of 1k failed under load, the chip never would've shipped in the first place, you're never going to see that. The linked bug is contemporary with the NaCl thread. How come the CPU vendor *most likely to have issues like the one you describe* is one of two whitelisted?

If by under load you mean not overclocked but under load. And as I'm sure you know, there was a fairly serious CPU correctness bug found by your employer during that timeframe, unsurprisingly against a whitelisted vendor.
