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 Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1423296 Title: Only one CPU core gets microcode updated Status in iucode-tool package in Ubuntu: New Status in linux package in Ubuntu: Confirmed Bug description: dmesg | grep -i microcode [ 0.000000] CPU0 microcode updated early to revision 0xa0b, date = 2010-09-28 [ 0.718229] microcode: CPU0 sig=0x1067a, pf=0x40, revision=0xa0b [ 0.718248] microcode: CPU1 sig=0x1067a, pf=0x40, revision=0xa07 [ 0.718266] microcode: CPU2 sig=0x1067a, pf=0x40, revision=0xa07 [ 0.718280] microcode: CPU3 sig=0x1067a, pf=0x40, revision=0xa07 [ 0.718286] microcode: CPU4 sig=0x1067a, pf=0x40, revision=0xa07 [ 0.718296] microcode: CPU5 sig=0x1067a, pf=0x40, revision=0xa07 [ 0.718308] microcode: CPU6 sig=0x1067a, pf=0x40, revision=0xa07 [ 0.718339] microcode: CPU7 sig=0x1067a, pf=0x40, revision=0xa07 [ 0.718441] microcode: Microcode Update Driver: v2.00 <tig...@aivazian.fsnet.co.uk>, Peter Oruba This is weird. All CPU cores showing same sig, but only one core's microcode updated? The machine has two physical CPUs, both are L5420, thus totally 8 CPU cores. --- ApportVersion: 2.14.1-0ubuntu3.7 Architecture: i386 DistroRelease: Ubuntu 14.04 InstallationDate: Installed on 2013-05-18 (640 days ago) InstallationMedia: Xubuntu 13.04 "Raring Ringtail" - Release i386 (20130423.1) IwConfig: lo no wireless extensions. eth1 no wireless extensions. eth2 no wireless extensions.
