On installing rawhide kernels I see: Disabling early microcode, because kernel does not support it. CONFIG_MICROCODE_[AMD|INTEL]_EARLY!=y The kernel options may have changed here so dracut needs to adjust to whatever it is now. % sudo dnf install kernel* Last metadata expiration check performed 0:13:16 ago on Fri Nov 6 11:38:40 2015.

This is because of upstream kernel commit fe055896c040df571e4ff56fb196d6845130057b and this hunk of code in dracut: if [[ $early_microcode = yes ]]; then if [[ $hostonly ]]; then [[ $(get_cpu_vendor) == "AMD" ]] \ && ! check_kernel_config CONFIG_MICROCODE_AMD_EARLY \ && unset early_microcode [[ $(get_cpu_vendor) == "Intel" ]] \ && ! check_kernel_config CONFIG_MICROCODE_INTEL_EARLY \ && unset early_microcode else ! check_kernel_config CONFIG_MICROCODE_AMD_EARLY \ && ! check_kernel_config CONFIG_MICROCODE_INTEL_EARLY \ && unset early_microcode fi [[ $early_microcode != yes ]] \ && dwarn "Disabling early microcode, because kernel does not support it. CONFIG_MICROCODE_[AMD|INTEL]_EARLY!=y" fi Since the options no longer even exist in the kernel, they won't show up in the resulting config-<kernel version> installed file even though the functionality is still actually in the kernel. I've emailed Harald and the upstream author of the kernel patch.
@harald: What's the plan forward here? You afaics fixed it upstream by http://git.kernel.org/cgit/boot/dracut/dracut.git/commit/?id=875426f2fc1360401ddb5f97c67df031e54958d5 which afaics made it to rawhide already. But everybody that installs a 4.4 kernel in f23 or earlier will get a initramfs without microcode update, which is not a good idea :-/
The Fedora 22 kernel 4.4.3 update just hit this. Guess an updated dracut needs to be pushed there also? $ rpm -qi dracut Name : dracut Version : 041 Release : 14.fc22 Architecture: x86_64 Install Date: Thu 25 Jun 2015 18:08:53 BST Group : System Environment/Base Size : 936320 License : GPLv2+ and LGPLv2+ Signature : RSA/SHA256, Thu 18 Jun 2015 20:52:45 BST, Key ID 11adc0948e1431d5 Source RPM : dracut-041-14.fc22.src.rpm Build Date : Tue 16 Jun 2015 13:58:42 BST
