Package: amd64-microcode Version: 3.20191218.1 Severity: normal On boot, the cpus are reported as having the following microcode version by the kernel:
microcode: CPU0: patch_level=0x0800820c But this is not the latest version of the microcode, which is 0x800820d & if I trigger a microcode load from the shell with echo 1 > /sys/devices/system/cpu/microcode/reload after booting then the microcode is updated to that newer version. I have checked & the initramfs does contain an uncompressed cpio archive containing the microcode file kernel/x86/microcode/AuthenticAMD.bin as expected. So either the kernel is not seeing this, or for some reason it does not contain the latest microcode version, despite that latest version being the one loaded from /lib/firmware/amd64-microcode when triggered post-boot. It would be nice to sort this out! Any suggestons as to where to start? cheers, Phil Armstrong -- System Information: Debian Release: bullseye/sid APT prefers testing APT policy: (500, 'testing'), (50, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.10.0-1-amd64 (SMP w/12 CPU threads) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8), LANGUAGE=en_GB:en Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled amd64-microcode depends on no packages.
