I have an 8th gen (i5-8400) processor installed in motherboard using the H370 chipset (Gigabyte H370 HD3) with factory default BIOS configuration running FreeBSD 11.2 amd64. Although the correct number of cores (6) and available frequencies are correctly detected only the lowest frequency is usable: # sysctl dev.cpu.0.freq_levels dev.cpu.0.freq_levels: 2801/65000 2800/65000 2700/61690 2500/55888 2400/52759 2200/47301 2100/44946 1900/39204 1800/37000 1700/34277 1500/29546 1400/27531 1200/22557 1100/20688 900/16549 800/14296 # sysctl dev.cpu.0.freq=2800 dev.cpu.0.freq: 800 -> 800 Accordingly powerd continues to try and raise the frequency in response to high system load but is unable to do so. If I disable 5 of the 6 cores in the BIOS then setting frequency as above is successful. Has this been reproduced and/or what are the next steps I should take to investigate? Attached is the obligatory dmesg which contains some complaints about ACPI firmware of unknown relevance? ---------- CPU: Intel(R) Core(TM) i5-8400 CPU @ 2.80GHz (2808.23-MHz K8-class CPU) Origin="GenuineIntel" Id=0x906ea Family=0x6 Model=0x9e Stepping=10 Features=0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE> Features2=0x7ffafbbf<SSE3,PCLMULQDQ,DTES64,MON,DS_CPL,VMX,EST,TM2,SSSE3,SDBG,FMA,CX16,xTPR,PDCM,PCID,SSE4.1,SSE4.2,x2APIC,MOVBE,POPCNT,TSCDLT,AESNI,XSAVE,OSXSAVE,AVX,F16C,RDRAND> AMD Features=0x2c100800<SYSCALL,NX,Page1GB,RDTSCP,LM> AMD Features2=0x121<LAHF,ABM,Prefetch> Structured Extended Features=0x29c67af<FSGSBASE,TSCADJ,SGX,BMI1,AVX2,SMEP,BMI2,ERMS,INVPCID,NFPUSG,MPX,RDSEED,ADX,SMAP,CLFLUSHOPT,PROCTRACE> Structured Extended Features2=0x40000000<SGXLC> Structured Extended Features3=0xc000000<IBPB,STIBP> XSAVE Features=0xf<XSAVEOPT,XSAVEC,XINUSE,XSAVES> VT-x: PAT,HLT,MTF,PAUSE,EPT,UG,VPID TSC: P-state invariant, performance statistics real memory = 17179869184 (16384 MB) avail memory = 16386461696 (15627 MB) Event timer "LAPIC" quality 600 ACPI APIC Table: <ALASKA A M I > FreeBSD/SMP: Multiprocessor System Detected: 6 CPUs FreeBSD/SMP: 1 package(s) x 6 core(s) ioapic0 <Version 2.0> irqs 0-119 on motherboard SMP: AP CPU #3 Launched!
