That file is way too big.  In fact, it is exactly the size of the newest
".dat" file from Intel.  The kernel doesn't grok that text format, the
microcode updates have to be converted to binary format, first.

I suggest you use "iucode_tool -S --write-earlyfw=ucode.cpio" to generate
your ucode.cpio.

You can find iucode-tool at:
