Still experiencing the same issue with newer kernel from testing. $ uname -a Linux debian 4.19.0-1-amd64 #1 SMP Debian 4.19.12-1 (2018-12-22) x86_64 GNU/Linux $ Package: ii linux-image-4.19.0-1-amd64 4.19.13-1 amd64Linux 4.19 for 64-bit PCs (signed) Thanks.
Bug#912596: cpufrequtils: cpufreq-info only shows 31 CPUs
Package: linux Followup-For: Bug #912596 (I sent this before, but for some reasons it didn't get into bts.) I have 32 cpus. So cpus indexed 0 - 31. Yes. * the cpu 0 - 30 show correct power/frequency info. * cpu 31 doesn't. Please inspect carefully my attached outputs of the tools used. So it only works for 31 CPUs, as in the subject. Thanks! -- System Information: Debian Release: buster/sid APT prefers testing APT policy: (500, 'testing'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.18.0-2-amd64 (SMP w/32 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled

I might be missing something, but ... 0 - 31 means a count of 32. Or do you have more than 32?

Thanks. Missing file in sys indicate it is an issue with kernel or my motherboard / CPU.

I have 16 cores, 32 threads. It only shows correctly first 31 CPUs. (cpu0 to cpu30). Last one cpu31 is missing some data.

So maybe it is a kernel bug of some sort. Ha! Yes, most likely an issue on the kernel end. I'm reassigning to linux-image4.18. -- mattia :wq!
