This is not new, but exists as far back as 2.6.17. I haven't reported it before because I figured that surely someone else had noticed it, but since it's still unfixed and I cannot find any mention of it on LKML, here we go.
I'm running a Core2 Duo 1.86GHz overclocked to 2.56GHz. Everything is normal with cpufreq scaling disabled. With cpufreq scaling enabled in the kernel, using any governor, /proc/cpuinfo indicates a maximum of the rated frequency rather than the actual frequency. Here it is under 100% utilization, with userspace governor and powernowd: [EMAIL PROTECTED]:~$ cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Core(TM)2 CPU 6300 @ 1.86GHz stepping : 6 cpu MHz : 1862.000 cache size : 2048 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 2 fpu : yes fpu_exception : yes cpuid level : 10 wp : yes flags : 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 ht tm syscall lm constant_tsc pni monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr lahf_lm bogomips : 5134.39 clflush size : 64 cache_alignment : 64 address sizes : 36 bits physical, 48 bits virtual power management: processor : 1 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Core(TM)2 CPU 6300 @ 1.86GHz stepping : 6 cpu MHz : 1862.000 cache size : 2048 KB physical id : 0 siblings : 2 core id : 1 cpu cores : 2 fpu : yes fpu_exception : yes cpuid level : 10 wp : yes flags : 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 ht tm syscall lm constant_tsc pni monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr lahf_lm bogomips : 5131.64 clflush size : 64 cache_alignment : 64 address sizes : 36 bits physical, 48 bits virtual power management: At idle it drops down to 1596.000 MHz reported. At boot the kernel doest report the correct frequency (2564.907), which agrees with the bogomips reported by /proc/cpuinfo as well. I haven't done any benchmarking to try to determine if perhaps freq scaling works as it should and just the reported frequency is incorrect.
