Hi everyone,

I have a new Acer Aspire 5100 laptop and a FreeBSD 6.2-RC1 installed. When I
shutdown the machine by "shutdown -p now" command, the machine will hang
after printing the "All Buffers Synced. Uptime: xx:xx" messages.

If I use the "reboot" command to reboot the machine, i got the same result
as the shutdown one.

I've tried to add the following lines into /etc/rc.conf, but it didn't work.

apm_enable="YES"
apmd_enable="YES"

I've tried to use some alternative command instead of "shutdown", but they
didn't work too:

acpiconf -s 5
init 0

I've tried to disable the ACPI function on start up, the system will crash
and reboot.

Could anybody kindly help or give some hints to solve this shutting down
problem?

Thanks.
