They are est/p4tcc/ichss. hint.ichss.0.disbled="1" helped me to avoid panics and those weired freqs in dev.cpu. Now it shows: cpu0: <ACPI CPU> on acpi0 est0: <Enhanced SpeedStep Frequency Control> on cpu0 p4tcc0: <CPU Frequency Thermal Control> on cpu0 and dev.cpu.0.freq_levels are as expected (and as it was earlier before this problem): 1600/-1 1400/-1 1225/-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 wbr, pluknet
