I want to share the following issue after upgrading the security rpm's on RHEL 7.9 machines include update of microcode_ctl rpm rpm -qa | grep microcod microcode_ctl-2.1-73.15.el7_9.x86_64 we noticed about the following kernel messages. [Sun Jun 4 13:12:19 2023] Microcode update for Intel Broadwell-EP/EX (BDX-ML B/M/R0; family 6, model 79, stepping 1; CPUID 0x406f1) CPUs is disabled as it may cause system instability. Please refer to /usr/share/doc/microcode_ctl/caveats/06-4f-01_readme and /usr/share/doc/microcode_ctl/README.caveats for details. [Sun Jun 4 13:13:35 2023] After installation of a new version of microcode_ctl package, [Sun Jun 4 13:13:35 2023] initramfs hasn't been re-generated for all the installed kernel packages. [Sun Jun 4 13:13:35 2023] The following kernel packages have been skipped: kernel-3.10.0-514.26.2.el7.x86_64. [Sun Jun 4 13:13:35 2023] Please re-generate initramfs manually for these kernel packages with the [Sun Jun 4 13:13:35 2023] "dracut -f --kver KERNEL_VERSION" command in order to get the latest [Sun Jun 4 13:13:35 2023] Intel CPU microcode included into early initramfs image for it, if needed. the current RHEL kernel version is uname -r 3.10.0-1160.80.1.el7.x86_64 so according to dmesg we can see that. dracut -f --kver KERNEL_VERSION so is it means that we need to set the current kernel version in command as dracut -f --kver 3.10.0-1160.80.1.el7.x86_64 or to set the kernel as defined in kernel message as dracut -f --kver kernel-3.10.0-514.26.2.el7.x86_64
