	Finally, running 'sysctl -a' by hand, when in single user I observe 
hang after hw.acpi.acline string. After reboot it continues fine with 
these strings:

hw.acpi.acline: 0 86
hw.acpi.battery.time: 72
hw.acpi.battery.state: 1
hw.acpi.battery.units: 1
hw.acpi.battery.info_expire: 5

	There is significant delay (about half a second) before battery 
strings. It seems sometimes this delay prolongs indefinitely.
	This is ASUS L5 notebook. Aug 9 kernel doesn't have this problem. If 
someone will look into it, it would be great.
