This is weird. All CPU cores showing same sig, but only one core's microcode updated? The machines have two physical CPUs, both are L5420, thus totally 8 CPU cores. ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- 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 linux package in Ubuntu: New 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.
