panics in 6.3-RELEASE in sound system

[Petr Holub]

Hi all,

this time I'm reporting panics in sound system :). I'm having
M-Audio Audiophile 192 sound card which got supported with the
new revision of sound system, so I have
sound
snd_envy24ht


The panic is reproducible when I start kcontrol (from fluxbox),
try to enable and configure soundsystem and then push the Test
button. I get the following crash (hand retyped DDB part as the
machine doesn't have serial port and I can't do it over firewire
as of now):

Any clues on this one?
