Description Stanislav Kozina 2018-05-03 15:24:43 UTC 
The updated ucode needs to be delivered for Broadwell EP/EX CPU models to mitigate Spectre vulnerability.
Broadwell EP/EX CPUs need updated microcode update sequence so this is blocker by bz1574579.
Comment 7 Eugene Syromiatnikov 2018-08-30 16:28:22 UTC 
Note: with microcode_ctl-2.1-45.el7, BDW EP/EX microcode is included, but is disabled by default due to reports of system hangs even with the updated kernels [1][2].
