Intel microcode not updating?

I am getting this error on booting up:

    [Firmware Bug]: TSC_DEADLINE disabled due to Errata; please update microcode to version (or later)

I see a possible mismatch between the firmware version in /boot/intel-ucode.img and the version reported by dmesg. If I am understanding all the info below correctly, microcode version 0xb00001c is being used, but /boot/intel-ucode.img contains version 0xb000021. Is that correct?

Re: Intel microcode not updating?

Is /boot on a separate filesystem?  If so was it mounted when you when the commands above?  If it was unmount /boot and vice versa then run the last command again.
Also the output of the following please

$ pacman -Q linux
$ file /boot/vmlinuz-linux
