Thanks for the info. I noticed that 2.3.47-7 has those changes merged
in, so I figured I'd give it a try.

(This is stock 2.3.47pre7 with Andrea's inode corruption fix applied,
from
ftp.kernel.org//pub/linux/kernel/people/andrea/patches/v2.3/2.3.47pre7/inode-corruption-2.gz)

At boot time, I get the normal message

isapnp: Scanning for Pnp cards...
isapnp: Card 'Creative ViBRA16X PnP'
isapnp: 1 Plug & Play card detected total

However, any attempt to open /dev/dsp results in

Soundblaster audio driver Copyright (C) by Hannu Savolainen 1993-1996
sb: dsp reset failed.

A quick check of /proc/isapnp showed the following suspicious lines:

Card 1 'CTL00f0:Creative ViBRA16X PnP' PnP version 1.0 Product version 1.0
  Logical device 0 'CTL0043:Audio'
    Device is not active
    [snip standard info]

At this point, I ran isapnp (userland tool), and checked back in
/proc/isapnp, and found

Card 1 'CTL00f0:Creative ViBRA16X PnP' PnP version 1.0 Product version 1.0
  Logical device 0 'CTL0043:Audio'
    Device is active
    Active port 0x220,0x330,0x388
    Active IRQ 5 [0x2]
    Active DMA 1,3

Trying to open /dev/dsp at this point worked fine. Since I'm not
passing the module /any/ parameters, this means that the kernel isapnp
must be working to some extent, because it did figure out correct
values for the card -- just didn't activate the device.

I've attached the .config used, and /proc/isapnp from before and after
running the userland utility, but what I've included above is all that
changed. Hope this bug report is of some use.
