In short term - no. Haven't tested it thoroughly. Results are the same (double interrupt rate according to `systat 1 -v`) for: * i386 and amd64 9-STABLE; * amd64 9.0. As everything related to timing/freq/acpi can be unpredictive I wouldn't recommend this to anyone. I own at least two Intel CPU's failing somewhere near timing/apic when loading cpufreq and enabling powerd. -- Sphinx of black quartz judge my vow.
