Just a typing error. Works now. Should I try to make buildworld? No problem. Please make sure hw.acpi.thermal.tz1.passive_cooling is 1 by typing `sysctl hw.acpi.thermal.tz1.passive_cooling' before trying. If hw.acpi.thermal.tz1.passive_cooling is 1, passive cooling should be working. You can see if passive cooling is actually working by setting hw.acpi.verbose to 1 using sysctl. While hw.acpi.verbose is 1, changing cpufreq by passive cooling is logged into /var/log/messages like: Feb 17 02:26:19 kasuga kernel: acpi_tz0: temperature 86.8C: decreasing clock speed from 1200 MHz to 1000 MHz Feb 17 02:26:23 kasuga kernel: acpi_tz0: temperature 78.8C: resuming previous clock speed (1200 MHz) Sincerely, -- Hajimu UMEMOTO @ Internet Mutual Aid Society Yokohama, Japan ume@mahoroba.org ume@{,jp.}FreeBSD.org http://www.imasy.org/~ume/
