Hello, I have noticed that FreeBSD gets the wrong CPU frequency levels for my Pentium M 2GHz. It used to work correctly with older versions of FreeBSD, but I noticed that this was not working properly when I installed 7.1 and this is still not working with -stable: Mar 30 15:08:03 mdaemon kernel: CPU: Intel(R) Pentium(R) M processor 2.00GHz (1995.14-MHz 686-class CPU) Mar 30 15:08:03 mdaemon kernel: Origin = "GenuineIntel" Id = 0x6d8 Stepping = 8 Mar 30 15:08:03 mdaemon kernel: Features=0xafe9fbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,TM,PBE> Mar 30 15:08:03 mdaemon kernel: Features2=0x180<EST,TM2> Mar 30 15:08:03 mdaemon kernel: AMD Features=0x100000<NX> Mar 30 15:08:03 mdaemon kernel: real memory = 1073577984 (1023 MB) Mar 30 15:08:03 mdaemon kernel: avail memory = 1032699904 (984 MB) Mar 30 15:08:03 mdaemon kernel: ACPI APIC Table: <DELL D05 > dev.cpu.0.freq: 1500 dev.cpu.0.freq_levels: 1500/-1 1312/-1 1200/-1 1050/-1 1000/-1 875/-1 800/-1 700/-1 600/-1 525/-1 450/-1 375/-1 300/-1 225/-1 150/-1 75/-1 dev.est.0.%desc: Enhanced SpeedStep Frequency Control dev.est.0.freq_settings: 1500/-1 1200/-1 1000/-1 800/-1 600/-1 Is there a way to fix this? Thank you! Pierre-Luc Drouin
