[FUG-BR] Compilação do kernel

[Mario Sergio Candian]

Boa tarde Pyth3r,

sobre esta sua placa de som, voce conseguiu fazer ela funcionar sem 
problemas no seu FreeBSD? Estou com uma placa como esta e aqui assim que 
comeca a tocar uma musica (uns 10 segundos depois) ela para e comeca a 
fazer "xiados". Ja tentei adicionando um patch no 
/usr/src/sys/dev/sound/pcm/ e mesmo assim nao fluiu.

root em cyberdine~% cat /dev/sndstat
FreeBSD Audio Driver (newpcm)
Installed devices:
pcm0: <VIA VT8235> at io 0xe000 irq 3 kld snd_via8233 (5p/1r/0v channels 
duplex default)

saida do pciconf -l:

pcm0 em pci0:17:5: class=0x040100 card=0x16171849 chip=0x30591106 rev=0x50 
hdr=0x00

root em cyberdine~% sysctl hw.snd.verbose=3
hw.snd.verbose: 1 -> 3

         [pcm0:play:0]: spd 22050/48000, fmt 0x10000010, flags 0x00000000,

Nao ha nenhum conflito de IRQ como pode ser visto abaixo:

root em cyberdine~% dmesg | grep irq
vr0: <VIA VT6102 Rhine II 10/100BaseTX> port 0xdc00-0xdcff mem 
0xdffffe00-0xdffffeff irq 11 at device 18.0 on pci0
fdc0: <floppy drive controller> port 0x3f7,0x3f4-0x3f5,0x3f2-0x3f3 irq 6 
drq 2 on acpi0
atkbdc0: <Keyboard controller (i8042)> port 0x64,0x60 irq 1 on acpi0
atkbd0: <AT Keyboard> irq 1 on atkbdc0
psm0: <PS/2 Mouse> irq 12 on atkbdc0 stray irq7
pcm0: <VIA VT8235> port 0xe000-0xe0ff irq 3 at device 17.5 on pci0

O conteudo do patch que eu apliquei foi este:

         { 0x574d4c04, 0x00, 0, "WM9704Q",       0 },

Estou usando FreeBSD 5.4-STABLE.

Qualquer dica eh bem-vinda! :)

Atenciosamente,
