Yeah, it can't work:

[ 1.366380] microcode: Microcode Update Driver: v2.2.
because that happens before the hdd driver has even been loaded yet.
My assumption that late_initcall() is late enough was wrong.
But that's ok - it was a weird use case anyway. One is supposed to use
early loading anyway.
Ok, lemme remove that loading attempt and test them more.
Thx.
