S3 problem: No PCI-interrupts after resume

S3 problem: No PCI-interrupts after resume

Hi,

I'm trying to get S3 Suspend to RAM running on my KT333CF-Board.
But after resuming: USB, soundcard, firewire + eth don't work (read as: no 
PCI-devices except IDE) . In proc/interrupts I saw no interrupts for these 
devices were incremented after resume. 
Kernel version is 2.6.7 with acpi update from len 
(acpi-20040326-2.6.7.diff.gz), but same for older versions of 2.6.x.

I've read the howto (http://forums.gentoo.org/viewtopic.php?t=122145), and 
tried to fix my DTSD. I extracted the DSDT and iasl gave me these warnings 
and my fixes:

dsdt.dsl-org   294:     Method (\_WAK, 1, NotSerialized)
Warning  2026 -                     ^ Reserved method must return a value 
(_WAK)

my fix:
        Return(Package(0x02){0x00, 0x00})

dsdt.dsl-org   324:             Store (Local0, Local0)

Error    1013 -                             ^ Method local variable is not

fixed with:

        {
            /* Store (Local0, Local0) */
        }

        Method (_SST, 1, NotSerialized)
        {
            If (LEqual (Arg0, 0x03)) {}
            If (LEqual (Arg0, 0x01)) {}
            If (LEqual (Arg0, Zero)) {}
            /* Store (Local0, Local0) */
        }
    }

Warning  2019 -                               ^ Not all control paths return a 
value (STM_)

fix:  
                    Return (TMD0)
<--- I don't know what to return here....

Full dsdt-files are attached. Just search for "cr7" to find my fixes.  I don't 
know if these fixes are correct, I expect they aren't. Iasl now accepted my 
fixes. I recompiled and tested (with  acpi-dsdt-initrd-patch). No luck.

I also tried acpi_os_name="Microsoft Windows" or "Microsoft Windows NT"  (as I 
could read in the dsl-file, search "_OS"). No success.

Please could you have a look at my "fixes" and tell me what to try next or 
which infos you need ?

Sincerally,
Carsten

Do you have APIC support in your kernel? If so, try disabling it. I get
no interrupts if I use APIC support, but everything is fine otherwise.
What should be setting up the APIC on resume?

Re: S3 problem: No PCI-interrupts after resume

[Carsten Rietzschel]

Hello,

thanks for your answer - I tried your suggestion, but it doesn't work:

without APIC: resumes, but no PCI-interrupts
with APIC: resumes, but no PCI-interrupts
with APIC+IOAPIC: does not resume (can't read anything, blank screen)

Also I tried "pci=noacpi" without success. Still no interrupts.

Regards,
Carsten
