system does not wake up sometimes

system does not wake up sometimes

[Peter Münster]

Hello,
very often, my system does not wake up at the specified time. I need to
press a key to resume.
The system goes to sleep the day before at about 22h30 with the following
commands:
modprobe genrtc
sleep 5
echo 2005-01-28 11:10:00 >/proc/acpi/alarm
sleep 5
echo 1 >/proc/acpi/sleep

What could be wrong?
I'm using Linux-2.6.10 and ASUS A7N8X-X ACPI BIOS Rev 1006.

Thanks in advance for any help! Please tell me, if you need more information.
Kind regards, Peter

did you mean alarm can't work only the specific time? Is there any rule?

Thanks,
Shaohua

No, I didn't find any rule. Sometimes the system really wakes up the right
time (Jan 22 11:10:00 gaston kernel: Back to C!), but very often it does
not. And this is not so good, because some cron-jobs don't get started at
the right time...

Greetings, Peter

Just try to set an alarm in system run time (doesn't do suspend/resume)
and see if ACPI interrupt increased (see /proc/interrupts). Please try
several times and report back. How about S3?

Thanks,
Shaohua

Now I've played around a little bit with /proc/acpi/alarm and I discover,
that it works exactly one time after reboot, and then never again.

Here is the kernel message when interrupt arrives:
ACPI-0286: *** Error: No installed handler for fixed event [00000004]

Here is the kernel message when interrupt arrives and system was sleeping:
Stopping tasks: ================================================|
Back to C!
APIC error on CPU0: 00(08)
    ACPI-0286: *** Error: No installed handler for fixed event [00000004]

And here the kernel message when I have to wake up the system by moving the
mouse:
Stopping tasks: =======================================================|

APIC error on CPU0: 00(08)
ACPI: PCI interrupt 0000:00:06.0[A] -> GSI 22 (level, high) -> IRQ 22

ACPI: PCI interrupt 0000:02:00.0[A] -> GSI 19 (level, high) -> IRQ 19
Restarting tasks... done

Concerning S3: it seems, that it does not work with X-Windows.

Cheers, Peter

Thanks for this link: now I'm using Linux 2.6.11-rc2 and everything seems
to be fine!
Best regards, Peter
