Description:
The following firmware bug error message is displayed every boot:
[Firmware Bug]: TSC_DEADLINE disabled due to Errata; please update microcode to version: 0xb2 (or later)

I originally assumed this was due to the microcode package being out of date, so I flagged it. However, this is not the case, the package is up to date, it is a bug.

Additional info:
intel-ucode 20170707-1
This task depends upon

There is nothing I can do about what Intel ships... Looks like you have to wait for the next ucode release.

Still wondering... What does 'journalctl -b | grep microcode' report?

So the problem here is that you simply haven't applied the intel ucode updates. That's a setup issue, not a package issue.

% bsdtar -Oxf /boot/intel-ucode.img | iucode_tool -tb -l -s 0x506e3 -
microcode bundle 1: (stdin)
selected microcodes:
001/147: sig 0x000506e3, pf_mask 0x36, 2017-04-09, rev 0x00ba, size 98304
