apmd - apmsleep does not wake up

[Thaly]

Hello all,

I'm running Linux (BusyBox with 2.4.21) on a PC104 board (Prometheus from Diamond Systems Corporation) and I installed apmd 3.0.2-18 on it. The problem is that, while apmsleep is able to put the computer to suspend, it does not wake up after the specified time. I have to press any key to wake it up and the command exits gracefully saying "Time Leap Detected" once I pressed a key.
The BIOS is a Phoenix BIOS 1.07 and the Modem ring detect and IRQ 3 are enabled.
I tried to check if the RTC driver is working right and I ran the demo program found on the Linux Kernel Documentation/rtc.txt. it works fine and the program is able to detect the RTC interrupt.
Also, apmsleep does not time out or anything. Just keeps the computer suspended until a key is pressed.
when I type cat /proc/drivers/rtc it displays something like this:
rtc_time : 22:34:37
rtc_date : 2004-02-12
rtc_epoch : 1900
alarm : 22:00:25
DST_enable : no
BCD : yes
24hr : yes
square_wave : no
alarm_IRQ : no
update_IRQ : no
periodic_IRQ : no
periodic_freq : 1024
batt_status : okay
I suspected the parameter alaram_IRQ and tried the ioctl function to enable it, but it still shows no.

Could anybody help me out?

Thanks very much.

Are you sure that your hardware really supports this?

Are you sure that your hardware really supports this?

yes, I checked the processor manual (ZFx86) and it does support power management. The bios also supports power management.
when I suspend the computer, I notice a significant drop in the power consumption, which means the system does sleep and comes back to normal state on the press of a key.
