I'm using fan-less Soekris (266 MHz) and EPIA (500 MHz) boards with -STABLE. Those boards have been emitting a very high pitched annoying whine, similar to a dog whistle. Not everyone I asked could hear it, but I was, and it was driving me crazy for months.
This whine stopped entirely the moment I put kern.hz="100" in /boot/loader.conf and rebooted. Quite relieving! Are there any reasons NOT changing kern.hz from the default 1000 back to 100? With my typical mix of desktop apps (EPIA) and networking / server (Soekris), everything seems to be running just as smoothly with 100 Hz than with 1000 Hz (testing now for two weeks without problems). Even playing videos with mplayer on the EPIA doesn't look different in any way. Is it okay to stay with 100 Hz with this type of low-speed CPU/boards? Or are there some compelling reasons not to? Thanks, -cpghost. -- Cordula's Web. http://www.cordula.ws/ _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
