Looks like it happens when notebook stats or shutdowns on batteries. Rebooting on AC power cures situation. But anyway - I do not think it is normal. Any suggestions ? I run 7-CURRENT here (19 Sep 05). powerd also enbled with default setup: % fgrep powerd /etc/rc.conf powerd_enable="YES" # Run powerd to lower our power usage. % -- Vladimir B.
