@dragestil Hmm, Phoronix quite interestingly seems to not cover GNU news that much unless something that can be taken as negative happens; https://www.gnu.org/software/gnuboot/web/news/gnuboot-december-2023.html

I don't believe that microcode even got compiled into the resulting images or was even used, as RC3 is operating exactly the same.

Multiple people worked on that codebase before, but it seems that only GNU developers found the problem and rectified it.
