Comment 57 for bug 1759920

Affects me on:
Intel(R) Xeon(R) CPU E3-1240 v5 @ 3.50GHz (family: 0x6, model: 0x5e, stepping: 0x3)

uninstall / disable intel-microcode has restored service on my DL20 G9 server.

Kernel cmdline dis_ucode_ldr worked to allow me to boot and uninstall the package.

> By any chance, do all of you have sssd installed?
This server has sssd, but unclear if its related.
