Hi Sekhar, I still seem to have problems taking the processor out of standby mode. Here is what I did # cat /proc/driver/rtc rtc_time : 00:04:23 rtc_date : 2000-01-01 alrm_time : 00:04:19 alrm_date : 2000-01-01 alarm_IRQ : yes alrm_pending : no 24hr : yes # root@arago:~# rtcwake -l -s 100 -d rtc0 wakeup from "standby" at Sat Jan 1 00:06:11 2000 rtcwake: short write # root@arago:~# cat /proc/driver/rtc rtc_time : 00:04:40 rtc_date : 2000-01-01 alrm_time : 00:06:11 alrm_date : 2000-01-01 alarm_IRQ : yes alrm_pending : no 24hr : yes Are there any else I need to enable?
