This changed on newer kernels. You will notice the kernel message DOES NOT mention any particular cpu anymore (before, it would have CPU# somewhere). That means the kernel is not going to repeat the message for every "CPU" unless they happen to need different microcode, which is not true for your machine. Please check /proc/cpuinfo output: it should list the updated microcode revision for all cores. -- Henrique de Moraes Holschuh <h...@debian.org> -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1423296 Title: Only one CPU core gets microcode updated To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/iucode-tool/+bug/1423296/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
