Re: ACPI problems on Athlon MP system

[Martin Siegert <siegert-z1KUqvL5UUQ@public.gmane.org>]

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
