unable to set alam using echo to /proc/acpi/alarm

unable to set alam using echo to /proc/acpi/alarm

[Ronald Wielink]

Dear all,
when I try setting the alarm to wake up my pc I get the following result:

[root@mithrandir acpi]# pwd
/proc/acpi
[root@mithrandir acpi]# cat alarm
2005-12-00 00:00:00
[root@mithrandir acpi]# echo 2005-12-15 17:18:19 > alarm
[root@mithrandir acpi]# cat alarm
2005-12-00 17:18:19
[root@mithrandir acpi]#

BTW, nothing happens at the echo'd date/time. Could someone please give me a
clue where to start looking?  I'm running fedora core 4, my mobo is an ASUS
P5S800-VM, the documentation on the motherboard states that ACPI is
supported. There is an option to turn acpi 2.0 on, but no difference...

Any help is greatly appreciated!

Regards,

Ronald

Do you have RTC driver compiled and loaded? CONFIG_RTC in kernel
.config?

It works well on different systems here :).

It works fine for me too here. 

One thing that I see, from the orig post: 

>[root@mithrandir acpi]# echo 2005-12-15 17:18:19 > alarm
>[root@mithrandir acpi]# cat alarm 
2005-12-00 17:18:19

Don't you need to ' that string since there is a space?
ie: 

echo '2005-12-15 17:18:19' > alarm

in order to get the year/month/date in correctly?

Okay, so the problem is in me. Could we get some documentation? It
would be useful to know what to expect, and it should probably end up
in Documentation/ somewhere.

Yup. Alarm is expected to wakeup the system from S3 sleep at a given
time.
Setting day, month and century is optional and depends on BIOS per ACPI
spec.
S4 alarm is also optional but maybe doesn't work on Linux (never tried).

Thanks,
Shaohua

i have seen a thinkpad wake up from S3 at the specified alarm time.
So it works somehow. Although i was never able to figure out if it was
woken up manually or by the alarm.
