Re: microcode updates and spectre variant 2

Intel has pulled the 20180108 microcode due to some CPUs crashing (uncommanded reboots are a crash), and they have reverted latest recommended to 20171117. And they appear to be recommending no longer deploying the 20180108 microcode, but I can't tell if they are directing this to firmware oems or

microcode updates and spectre variant 2

Koji contains linux-firmware-20171215-82.git2451bb22.fc27 which contains intel-ucode from 20171117. But I don't know if this firmware contains the microcode required to completely secure from Spectre variant 2. https://access.redhat.com/articles/3311301 "This vulnerability requires both updated
