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
9: 1 XT-PIC acpi
10: 111 XT-PIC pcnet_cs
11: 8 XT-PIC Texas Instruments PCI1420, Texas Instruments PCI1420 (#2)
12: 420 XT-PIC PS/2 Mouse
14: 28392 XT-PIC ide0
15: 8 XT-PIC ide1
NMI: 0
ERR: 0
root@amd:~#

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

Kernel command line: auto BOOT_IMAGE=pavel ro root=304
BOOT_FILE=/boot/bvmlinuz enableapic vga=0x0317 hdc=ide-scsi pci=biosirq
ide_setup: hdc=ide-scsi

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