pci=biosirq... Is the machien having fun with me?

[Pavel Machek]

Hi!

On hp omnibook xe3, Sound is working poorly. Its maestro3 *plays*, but
repeats portions.... No wonder.... It probably did not receive correct
irq (while playing music!):

root@amd:~# cat /proc/interrupts
           CPU0
  0:      14014          XT-PIC  timer
  1:       1134          XT-PIC  keyboard
  2:          0          XT-PIC  cascade
  5:          0          XT-PIC  Allegro

 14:      28392          XT-PIC  ide0

NMI:          0
ERR:          0
root@amd:~#

So I did as adviced, appended pci=biosirq to commandline:

I did specify pci=biosirq, and it *still* suggests me using
pci=biosirq. Smells like bug. Linux-2.4.14.

Okay, that message was pretty confusing. I had to select PCI_GOANY=y
for pci=biosirq to be recognized...

But /proc/interrupts still looks the same, and sound is still funny.

pavel@amd:~$ cat /proc/interrupts
           CPU0
  0:      16893          XT-PIC  timer
  1:        930          XT-PIC  keyboard
  2:          0          XT-PIC  cascade
  5:          0          XT-PIC  Allegro
  9:          1          XT-PIC  acpi
 10:        172          XT-PIC  pcnet_cs
 11:          8          XT-PIC  Texas Instruments PCI1420, Texas Instruments PCI1420 (#2)
 12:          6          XT-PIC  PS/2 Mouse
 14:      36712          XT-PIC  ide0
 15:          8          XT-PIC  ide1

pavel@amd:~$

What else should I try?
