/proc/acpi/alarm not working

[Lorenzo Colitti <lorenzo-Z4WAQ3j+MphBDgjK7y7TUQ@public.gmane.org>]

Hi,

I am trying to use /proc/acpi/alarm to wake my laptop from S3 and go 
into S4 after a fixed amount of time. But I can't get /proc/acpi/alarm 
to work.

I tried 'echo "2005-06-08 12:47:00" > alarm', both using local time and 
with 2 hours plus or minus since I'm not sure if the alarm file is in 
UTC or not.

A 'cat alarm' displays the time I set it to, and there are no errors in 
dmest, but nothing seems to happen. If the laptop is on, I see no acpi 
event being triggered. If it's in S3, it doesn't wake up unless I press 
the power button.

Is there something I'm doing wrong? If not, how do I debug this?


Cheers,
Lorenzo

P.S. This works on Windows, so the DSDT should support it...
