ACPI-wakeup

Zitat

I'm using linvdr 0.7 with some pathces. ACPI-wakeup works really nice on my
Asus CUBX motherboard. But, when I use Debian 3.1 on the same machine and same poweroff.pl script--> acpi-wakeup is not working....!?!?!?!

ACPI is enabled on 2.6.16.3 kernel and APM is disabled.

the linvdr poweroff.pl calls the busybox poweroff - afaik there is no busybox on debian3.1 - so you have to change that line ...

this is the line

sub PowerOff {
#  system("/bin/busybox poweroff") if(!$DEBUG);
# there is no busybox 
    system("/sbin/poweroff") if(!$DEBUG);
}

Maybe Debian syncs the hardware time with the current system time AFTER programing the Bois Timer. ( echo WAKEUPTIME > /proc/acpi/alarm)

Look for
HWCLOCKACCESS=no in /etc/default/rcS or an existing /etc/adjtime file

also have a look to /etc/init.d/hwclock.sh

At a normal Debian shutdown process the hardware clock is synced. This may be you problem.

The essence is -- you can't just copy the poweroff.pl to a Debian system and expect it to work. You have to find the right position for setting the alarm clock in the Debian init scripts and implement it there. Due it's a simple "echo" to /proc/acpi/alarm, that's not very difficult.

please try:

/etc/init.d/hwclock.sh:

stop|restart|reload|force-reload)


==>         ACPITIME=`cat /proc/acpi/alarm`
                if [ "$HWCLOCKACCESS" != no ]
                then
                    if [ "$VERBOSE" != no ]
                    then
                        echo "Saving the System Clock time to the Hardware Clock
..."
                    fi
                    [ "$GMT" = "-u" ] && GMT="--utc"
                        /sbin/hwclock --systohc $GMT $BADYEAR
                    if [ "$VERBOSE" != no ]
                    then
                        echo "Hardware Clock updated to `date`."
                    fi
==>              echo "$ACPITIME" > /proc/acpi/alarm
