Comment 4 Jeff Bastian 2020-06-22 21:21:55 UTC
Verified with microcode_ctl-2.1-61.10.el7_8.

Sandy Bridge EP updated automatically (no need for a "force" file anymore).

The failed tasks are due to the blacklisted microcode for the CPU models due to the potential for a system freeze at boot.  The failure is because the system is not running the latest version of the microcode due to the blacklist, thus the failure is expected and it means the blacklist is working.

When the microcode update was forced, the 06-4e-03 system did hang on boot and I had to interrupt grub and add dis_ucode_ldr to get the system to boot and finish running the job.
