Hi,

I'm trying to get ACPI wakeup working on an ASRock K8NF6G-VSTA box, but 
with no success yet:

- Setting the wakeup time manually in the BIOS setting does work.
- The box can be woken on PS/2 keyboard.
- Using either rtcwake or writing directly to 
/sys/class/rtc/rtc0/wakealarm as per 
http://www.mythtv.org/wiki/ACPI_Wakeup#Manually_test_wakealarm produces 
the expected contents of /proc/driver/rtc:

root at erzulie:~# cat /proc/driver/rtc
rtc_time    : 20:35:46
rtc_date    : 2013-03-27
alrm_time    : 20:38:43
alrm_date    : 2013-03-27
alarm_IRQ    : yes
alrm_pending    : no
update IRQ enabled    : no
periodic IRQ enabled    : no
periodic IRQ frequency    : 1024
max user IRQ frequency    : 64
24hr        : yes
periodic_IRQ    : no
update_IRQ    : no
HPET_emulated    : no
BCD        : yes
DST_enable    : no
periodic_freq    : 1024
batt_status    : okay

- I have tried both with RTC wakeup enabled and disabled in the BIOS.
- I have tried both normal shutdown (shutdown -h) and poweroff -f.

Any suggestions?
