This may be caused by the 5.11 AMD CPU frequency / CPPC fix. Steps to Reproduce:=20 cat /proc/cpuinfo or lscpu Actual Results: Reported operating frequency far beyond actual. (Over 6 GHz) Expected Results: Reported actual operating frequency. Build Date & Hardware: Build 2021-02-15 on Gentoo CPU: AMD Ryzen 9 3900X 12-Core Processor AMD AGESA: ComboAM4PIV2 1.2.0.0 CPPC: enabled Additional Information: /sys/devices/system/cpu/cpu*/cpufreq/scaling_cur_freq reported correct frequency. --=20 You may reply to this email to add a comment.
