Hi, on a dual INTEL(R) XEON(R) PLATINUM 8558 system, we've upgraded from 6.8.X to 6.9.4 and noticed that turbostat is no longer working. turbostat: /sys/devices/system/cpu/intel_uncore_frequency/package_01_die_00/current_freq_khz: open failed: No such file or directory ls -la /sys/devices/system/cpu/intel_uncore_frequency/ total 0 drwxr-xr-x 4 root root 0 Jun 17 15:29 . drwxr-xr-x 204 root root 0 Jun 15 21:45 .. drwxr-xr-x 2 root root 0 Jun 17 15:29 package_00_die_00 drwxr-xr-x 2 root root 0 Jun 17 15:29 package_01_die_01 Seems to be missing a die on each package? Best regards, Darius.
