As a result, CPU usage indicates above 100% nearly all of the time, and immediately reverts the CPU to its maximum frequency [as it should]. 2. setting the sysctl variable dev.cpu.0.freq manually to any of the frequencies listed in dev.cpu.0.freq_levels causes the same thing to happen. 3. hardware: HP Pavilion dv7 laptop with amd64 dual core, running FreeBSD 7.2 pre-release from April 28 [this problem was in earlier 7.x versions as well]. 4. eliminating the cpufreq driver by adding hint.acpi_throttle.0.disabled="1" to loader.conf only disabled the ability to change frequencies [no other driver was available to do the job] so there's no obvious workaround. 5.
