Previously, the dracut tool incorrectly copied the AMD family 15h microcode into the Initial RAM File System (initramfs) on systems with AMD family 16h processors. Consequently, the microcode on such systems was not updated early enough in the boot process. This update fixes dracut to copy the correct AMD family 16h microcode into initramfs, and the microcode is now correctly updated in the early phase of the boot process.
This bug has been copied from bug #1476039 and has been proposed to be backported to 7.2 z-stream (EUS).
*** Bug 1529310 has been marked as a duplicate of this bug. ***
Reproduced on RHEL-7.2 GA
Verified with dracut-033-360.el7_2.3, the correct microcode was included in the early CPIO image depending on the CPU family.
Moving to VERIFIED.
