Hallo,
yum MUST disable RTC-Wakeup in the BIOS of your motherboard. In my case I MUST write the wakeuptime
twice:
example:
----------------------------------------------------------------------------
if [ ! -z $1 ]; then
newtime=$(($1 - 60 )) # 1 minutes earlier
logger "VDR-Timer: $1"
logger "BIOS-Timer: $newtime"
echo $(/bin/unix2iso8601 -u $newtime) >/proc/acpi/alarm
echo $(/bin/unix2iso8601 -u $newtime) >/proc/acpi/alarm
logger "ACPI-Read: $(cat /proc/acpi/alarm)"
else
logger "VDR-Timer: keine Zeitübergabe"
fi
----------------------------------------------------------------------------
