New question #77735 on Ubuntu:
https://answers.launchpad.net/ubuntu/+question/77735

My PC clock is set to local time and I use the folowing script to setup ACPI Wakeup : 

#! /bin/bash
SECS=`date -u --date "$1" +%s`
echo 0 > /sys/class/rtc/rtc0/wakealarm
echo $SECS > /sys/class/rtc/rtc0/wakealarm
cat /proc/driver/rtc


When I use this script, shutdown my PC and wait for the wakeup everything works fine.


But If I manually re-start and stop my PC before date/time alarm my PC don't Wakeup.

alrm_time is not changed, alrm_date is changed to ****-**-** (it seems that my BIOS don't use date for wakeup) and alarm_IRQ is set to no


it's like something reset acpi wakeup at reboot.


For information everything was OK with /proc/acpi/alarm on Gutsy (my PC wakeup everynight at 01:00 without have to setup acpi wakeup date/time at shutdown - no date, only time in BIOS wakeup settings)
