I run low power workstations here which are intended to be used in a lab environment, and I would very much like to have working power-saving features (otherwise the whole setup is quite useless). Can I somehow help debugging this, should I file a PR or are there any further recommended things to do? cu Gerrit _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
