For AMD, a similar mechanism is available, but since I don't own an AMD CPU, I cannot implement this. This causes problems, since the microcode update is no longer triggered automatically on boot (since microcode is no longer a module). If you want to update the AMD ucode, you probably need to run echo > /sys/devices/system/cpu/microcode/reload on boot. I hope someone with an AMD CPU will look into this.
I generated amd-ucode.img with the following commands: $ mkdir -p kernel/x86/microcode $ cat /usr/lib/firmware/amd-ucode/microcode_amd*.bin \ >kernel/x86/microcode/AuthenticAMD.bin $ find kernel | bsdcpio -o -H newc -R 0:0 >amd-ucode.img In syslinux.cfg I specified (w/ separate /boot partition): INITRD ../amd-ucode.img,../initramfs-linux.img While the above works fine on my desktop and microcode is updated early like it's supposed to, my laptop with the exact same configuration just hangs at the message "Booting the kernel."
