As soon as that happens, the system freezes hard. Trying powerd in the foreground with -v shows that it decreased the frequencies a few times, but then hangs the system. So I've tried this manually: # sysctl dev.cpu.0.freq_levels dev.cpu.0.freq_levels: 1985/-1 1736/-1 1488/-1 1240/-1 992/-1 744/-1 496/-1 248/-1 # sysctl dev.cpu.0.freq dev.cpu.0.freq: 1985 powerd freezed the system after reaching 1240 when trying 992. If I set the frequency manually down to 1240 with: # sysctl dev.cpu.0.freq=1240 everything's fine. But as soon as I try setting it further down (992, 744, 496 or 248), the system freezes too, just the same as with powerd. This is 100% reproducible. So what's going on here? Thanks, -cpghost.
