How do you check the current version of microcode in use? Since amd64-microcode package is so outdated in Debian, I updated microcode files manually from the upstream Linux firmware repo, putting them in /usr/lib/firmware/amd-ucode. Then I ran sudo dpkg-recoconfigure amd64-microcode hoping it will update it. On next reboot I have the same version as before (basically what's in my UEFI) according to dmesg. Doing echo 1 > /sys/devices/system/cpu/microcode/reload and checking /proc/cpuinfo I also don't see any change. Thanks, Shmerl.
