I can set the cpu frequency via sysctl. Well, it's not entirely perfect since on this machine it allows only two frequencies: dev.cpu.0.freq_levels: 1739/-1 869/-1 A more software-related solution with the kernel halting execution would be somewhat cooler, but then again, I probably don't need it :) Atis _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
