On FreeBSD 9.1-PRERELEASE (i386) changing dev.cpu.0.freq (default: 600) has no effect; e.g. building a kernel takes approx. 2,5 hours (at 600 MHz and 1600 MHz). I've also removed "device cpufreq" from my kernel. In comparison to my Atom Netbook (N270 @1.6GHz) my net6501-70 performs rather slow. :-( Is there a patch for FreeBSD? I will try OpenBSD-current soon. -- Herbert _______________________________________________ Soekris-tech mailing list [email protected] http://lists.soekris.com/mailman/listinfo/soekris-tech
