One other thing to try, Mike, is boot with "dis_ucode_ldr". See whether
that makes it go away.

That's like quadruple-checked :-)

Hmm, maybe I did the diff wrong?

So this is how I generated it:

$ git diff tip/x86/microcode~1..tip/x86/microcode

meaning that I want to see what the merge commit changed. That's why
this pulled in the fpu/core.c hunk which is new in urgent.

In any case, the merge looks ok to me, I'll be testing it anyway in the
coming days so I'll let you know if anything goes nuts.

Thanks!
