I repeated my tests just after I installed Intrepid. Here are my results: 1) echo 0 > /sys/class/rtc/rtc0/wakealarm doesn't work due to Permission denied error
2) I found workaround : usern...@comp:~$ sudo sh -c 'echo 0 > /sys/class/rtc/rtc0/wakealarm' usern...@comp:~$ sudo sh -c 'echo `date "+%s" -d "+ 5 minutes"` > /sys/class/rtc/rtc0/wakealarm' usern...@comp:~$ cat /sys/class/rtc/rtc0/wakealarm usern...@comp:~$ cat /proc/driver/rtc rtc_time : 23:20:51 rtc_date : 2009-01-21 alrm_time : 23:25:29 alrm_date : ****-**-21 alarm_IRQ : no alrm_pending : no 24hr : yes periodic_IRQ : no update_IRQ : no HPET_emulated : no DST_enable : no periodic_freq : 1024 batt_status : okay usern...@comp:~$ It is interesting "cat /sys/class/rtc/rtc0/wakealarm" gives no output. Computer didn't boot at specified time. Manual inspection of BIOS setting revealed correctly changed time (23:25:29). However date (of month) was wrong - 1. 3) I repeated step 2 with changed /etc/default/rcS file according to advice in http://www.mythtv.org/wiki/ACPI_Wakeup Same result as in (2) in BIOS. Warning! I had serious problem to boot then! Finally, I had to boot using live CD and reject changes in /etc/default/rcS in order to boot again. I am strongly interested to turn it working. So far without success. I am planning to test Fisslefink's solution next time.
