FYI it looks like this package does not contain the latest microcode rev 0xb00002a for cpuid 0x000406f1 (Broadwell E/EX)

@tobbe did you run "dracut -f" before reboot - otherwise it's only available after the next kernel update generating a new initramfs - these days micro-code updates needs to be early loaded because they can remove features from the CPU

that's not the issue, i looked at the actual microcode versions provided in the package with iucode_tool and then i compared revision against the pdf from intel ( https://newsroom.intel.com/wp-content/uploads/sites/11/2018/03/microcode-update-guidance.pdf )

# iucode_tool -L 06-4f-01
microcode bundle 1: 06-4f-01
  001/001: sig 0x000406f1, pf_mask 0xef, 2017-03-01, rev 0xb000021, size 26624

@tobbe @hreindl I did also get an "old" microcode (from January 21) for a Haswell (Intel G1840), was expecting something more recent.

looking at https://www.heise.de/security/meldung/Spectre-Luecke-Intels-Microcode-Updates-fuer-Linux-und-Windows-3994347.html (german but near bottom is a table) this updates are more for the oldest generations (SandyBridge/IvyBridge) which did until now not get any update at all and since i have both generations i can confirm that
