/sys/class/rtc/rtc0/wakealarm doesn't work. after the command cat /sys/class/rtc/rtc0/wakealarm, i inputed #sh -c "echo 0 > /sys/class/rtc/rtc0/wakealarm", and also, input #sh -c " echo `date '+%s' -d '+ 3 minutes'` > /sys/class/rtc/rtc0/wakealarm" then shutdown. but no result has come.
anybody who knows about this..please inform me of those things..
wakealarm doesn't work!
Re: wakealarm doesn't work!
maybe centos6 doesn't support /sys/class/rtc/rtc0/wakealarm. so i fix rtc alarm on cmos. with hardware supporter i can power on booting one time.
