Abit KV7 ACPI: Unable to set IRQ for PCI Interrupt Link [ALKD] (likely buggy ACPI BIOS)

Abit KV7 ACPI: Unable to set IRQ for PCI Interrupt Link [ALKD] (likely buggy ACPI BIOS)

Post by ekkard gerlac » Thu, 04 Nov 2004 09:34:28



Anybody here who is working with abit KV7? - Mine has trouble with
2.4.26 (Suse 8.2). I get the following messages while booting:

[...]
IRQ19 -> 0:19
IRQ21 -> 0:21
IRQ22 -> 0:22
.................................... done.
ACPI: Unable to set IRQ for PCI Interrupt Link [ALKD] (likely buggy ACPI
BIOS).
Aborting ACPI-based IRQ routing. Try pci=noacpi or acpi=off
  - die gleiche Meldung dann ca 10 Male -
[...]

Sound doesn't work. Any other hardware seems to work (USB, 2nd
parport-card, etc). Mainboard works quite fast with Barton 2500.

The onboard-Sound:
00:11.5 Multimedia audio controller: VIA Technologies, Inc. VT8233 AC97
Audio Controller
(rev 60)
         Subsystem: ABIT Computer Corp.: Unknown device 1408
         Flags: medium devsel, IRQ 22
         I/O ports at e000 [size=256]
         Capabilities: [c0] Power Management version 2

With google I don't find much. "ACPI: Unable ....[ALKD]" - a german
thread "KT400A: Acpi-Bios oder Kernel buggy?" concerning the same KT 600
  Chipset but on a Epox EP-8K9A9+  mainboard. The thread is quite old
(one year) an I think that some bugs in 2.4.21 will be corrected in my
2.4.26, isn't?

I don't want to turn off ACPI! I want to use ACPI for e.g. current
saving during night. I need a low cost mainboard for next one or two
dozent mainboards for office PC's.

Is ACPI of KV7 BIOS buggy? shall I update BIOS? A problem of 2.4.26?
Solved with 2.6.X?

I just tested my "old" 2.4.20 kernel (belongs to Suse 8.2).
recompiled alsasound - and it works! Obviously 2.4.26
is buggy, not ACPI BIOS!

Can somebody here tell me whether 2.4.27 oder .28 are not so buggy? Or
.24 ord .25? - I've not so much time to test all kernels ..

1. ACPI IRQ routing (was [ACPI] ACPI source release updated (200 11205))

Hi Kai,

I also got ACPI IRQ routing working on a system over the weekend. Sounds
like yours is better, so great we'll adopt yours. Thanks for stepping up on
this.

<shrug>. Once we get it working, we can get it working right, and save the
1K.

Like I said above, I think it's too early to be optimizing this code. My
main concern was more about integrating ACPI into pci-irq.c in a readable
manner. It is pretty $PIR-specific (no surprise there). Anyways let me work
with your new code and I will be able to comment more.

At this point, I'd think one to *enable* it would be better until the code
is tested more.

Regards -- Andy
