For that particular processor model, there appears to be microcode
updates for four steppings: 9 10 11 and 12. My model is stepping
9, so it appears to be early commercially sold version of that
model. Probably more problems on it than on later steppings.

I'm not alone with latest Intel microcode problems. Debian for
example reverted microcode to older microcode version on some
Intel processor models because of hangs on warm reboots. Those
reverts were not for same processor model as my processor, but
they do indicate "not everything OK" situation with latest Intel

My laptop computer was made by Dell, and Dell has been really good
at providing new BIOS updates (that don't require Microsoft OS to
update). More than once they have provided new BIOS to fix some
security flaw that was still embargoed. The information about that
security flaw then became publically known later after embargo

Now that I have learned about the instability of latest two
microcode updates for my laptop's processor, it isn't difficult to
connect the dots why Dell is still shipping 3rd latest microcode
in their latest BIOS update for that laptop computer.
