I just tested with GRUB and it doesn't seem to work. I added /intel-ucode.img in first position in every /boot/grub/grub.cfg's initrd lines (standard and ck-kernels + fallback entries), upgraded my system (update contained new intel-ucode and linux) and rebooted on linux-ck (which is still at 3.16.6-2-ck if that matters). Rebooted fined, but : # journactl -b | grep microcode oct. 23 00:49:50 arch-clevo kernel: microcode: CPU0 sig=0x306a9, pf=0x10, revision=0x19 oct. 23 00:49:50 arch-clevo kernel: microcode: CPU1 sig=0x306a9, pf=0x10, revision=0x19 oct. 23 00:49:50 arch-clevo kernel: microcode: CPU2 sig=0x306a9, pf=0x10, revision=0x19 oct. 23 00:49:50 arch-clevo kernel: microcode: CPU3 sig=0x306a9, pf=0x10, revision=0x19 # journalctl | grep microcode | tail -100 ## -b -1 is broken, displays stuff from the beginning of my log... oct. 22 23:43:39 arch-clevo kernel: microcode: CPU0 sig=0x306a9, pf=0x10, revision=0x1b oct. 22 23:43:39 arch-clevo kernel: microcode: CPU1 sig=0x306a9, pf=0x10, revision=0x19 oct. 22 23:43:39 arch-clevo kernel: microcode: CPU1 updated to revision 0x1b, date = 2014-05-29 oct. 22 23:43:39 arch-clevo kernel: microcode: CPU2 sig=0x306a9, pf=0x10, revision=0x19 oct. 22 23:43:39 arch-clevo kernel: microcode: CPU2 updated to revision 0x1b, date = 2014-05-29 oct. 22 23:43:39 arch-clevo kernel: microcode: CPU3 sig=0x306a9, pf=0x10, revision=0x1b Just to give more info: # cat /boot/grub/grub.cfg | grep initrd initrd /intel-ucode.img /initramfs-linux-ck.img initrd /intel-ucode.img /initramfs-linux-ck.img initrd /intel-ucode.img /initramfs-linux-ck-fallback.img initrd /intel-ucode.img /initramfs-linux.img initrd /intel-ucode.img /initramfs-linux-fallback.img $ ls -l /boot total 61597 drwxr-xr-x 6 root root 1024 23 oct. 00:42 grub -rw-r--r-- 1 root root 20387566 20 oct. 23:36 initramfs-linux-ck-fallback.img -rw-r--r-- 1 root root 6574230 20 oct. 23:36 initramfs-linux-ck.img -rw-r--r-- 1 root root 20704983 23 oct. 00:47 initramfs-linux-fallback.img -rw-r--r-- 1 root root 6831046 23 oct. 00:47 initramfs-linux.img -rw-r--r-- 1 root root 648704 12 oct. 14:05 intel-ucode.img drwx------ 2 root root 12288 4 déc. 2013 lost+found -rw-r--r-- 1 root root 4026016 15 oct. 15:05 vmlinuz-linux -rw-r--r-- 1 root root 3887072 20 oct. 02:48 vmlinuz-linux-ck $ uname -a Linux arch-clevo 3.16.6-2-ck #1 SMP PREEMPT Sun Oct 19 20:46:56 EDT 2014 x86_64 GNU/Linux Downgrading to previous intel-ucode not to remain with no microcode update...
