Re: ACPI problems on Athlon MP system

Hi again,

I patched/compiled linux-2.4.21-pre2 with the acpi-20021212-2.4.20
patch. Now the machine does not even boot anymore. Here is the last
part of the boot messages


AMD7411: not 100% native mode: will probe irqs later
    ide0: BM-DMA at 0xf000-0xf007, BIOS settings:hda:DMA, hdb:pio

Partition check:

hda: dma_timer_expiry: dma status == 0x24


and at this point the machine hangs forever. I then rebooted the machine
with the "noapic" kernel flag and this time it boots but I get a lot of
"APIC error on CPU1: 40(40)" messages. A recent snapshot from syslog is:

Jan 14 19:22:40 test2 kernel: APIC error on CPU1: 40(40)
Jan 14 19:23:11 test2 last message repeated 3912 times
Jan 14 19:24:12 test2 last message repeated 6393 times
Jan 14 19:25:13 test2 last message repeated 6106 times
Jan 14 19:26:14 test2 last message repeated 6116 times
Jan 14 19:26:57 test2 last message repeated 6243 times

However, the "poweroff" command now works!

Is there a conflict between ACPI and APIC or is there a way of getting
the best of both worlds? I.e., can I use the acpi-20021212-2.4.20
without having to set the "noapic" flag? (it is entirely possible
that I misconfigured the kernel in some way)

Cheers,
Martin

Hi Martin,

the ACPI support in the 2.4 kernel series is very old (from autumn
2001 if I remember correctly), so you should use the ACPI patch from
http://sourceforge.net/projects/acpi; in your case

    http://prdownloads.sf.net/acpi/acpi-20021212-2.4.20.diff.gz

(This patch applies cleanly against linux-2.4.21-pre2 from kernel.org
even though it was done for 2.4.20.)

The Intel people are trying to get an updated ACPI version into 2.4,
but I guess this will not happen before 2.4.22. The 2.5 kernel series
does already include a current ACPI version.

Good luck,
Arndt

Hi,

I am not sure whether this is the correct place to ask this question,
but hopefully you can point me in the right direction.

Here is the problem:
I am trying to get the "poweroff" command working on an Athlon MP
(Tyan S2462) system (linux-2.4.21-pre2; otherwise RedHat 7.3).

The machine has ACPI enabled in the bios. When I compile the kernel
with ACPI disabled, the poweroff command shuts down the system, but
does not shut off the power (it acts exactly like the halt command).
In order to shutoff the machine I must press the power switch.

When I compile the kernel with ACPI enabled the situation is worse:
the halt and poweroff commands still work in exactly the same way
(shutdown the system), but now I cannot switch off the machine
anymore: pressing the power switch has absolutely no effect
(regardless of how long I hold the switch). The only way to
switch off the machine is to either pull the power cord or to
press the reset button on then the power switch (which will then
switch off the machine when it reboots).

What am I doing wrong? Am I missing some kernel switches, options?
Do I need additional software?

Any help or suggestions, hints are appreciated!

Thanks in advance,

Martin
