> Why two FNCLEX? There is a behavior on some CPUs where "out 0xf0" can leave IGNNE# active, but you can clear it after the "out" by running "fnclex". Why are there two of them? Either the "out 0xf0" is affected by IGNNE# being active, or maybe the original draft had one "spin, out, fnclex" and that whole block of code was just copy+pasted when they added the second one.
