    After I updated to this version of amd-microcode, apt update triggers check that
    keeps telling me I'm not running the latest amd64 cpu microcode and I should reboot.

    I rebooted, and even regenerated a new initramfs (not updated existing one)
    but microcode version does not change.

    Tried to changedefault config value from auto to eraly but no change.

    What else can I check?
