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?
