From digging around the codebase (I'm just a noob), it seems from my understandi= ng that it's something introduced in sys/x86/cpufreq/hwpstate_intel.c, which is quite recent (commits starting on January 22, 2020, not merged into 12.x, a= nd few enough commits for me to keep track of: git log sys/x86/cpufreq/hwpstate_intel.c). Once I get time I could try compiling ea= ch of the significant revisions starting with the one just before the introduc= tion of the Speed Shift stuff and seeing which one breaks first. Could be wrong about all of this though. --=20 You are receiving this mail because: You are the assignee for the bug.=
