[Openvortex-dev] Kernel Oops with snd-au8830 on AMD64 platform

[Toby Haynes]

I have a lousy sound chip (via-82xx) on my motherboard so I'm keen to 
get my venerable Aureal Vortex 2 card up and running on my new box. 
However, it is an AMD64 box and it's causing a kernel Ooops when I try 
and initialize alsa. I'm wondering how many other people have tried this 
combo ...

The original /etc/modprobe.conf file:

alias eth0 via-rhine
alias sound-slot-0 snd-au8830
options snd-via82xx dxs_support=4
install scsi_hostadapter /sbin/modprobe sata_via; /bin/true
remove snd-via82xx /sbin/modprobe -r snd-pcm-oss; /sbin/modprobe 
--first-time -r --ignore-remove snd-via82xx
install snd-via82xx /sbin/modprobe --first-time --ignore-install 
snd-via82xx && { /sbin/modprobe snd-pcm-oss; /bin/true; }
install usb-interface /sbin/modprobe uhci-hcd; /sbin/modprobe ehci-hcd; 
/bin/true
alias eth1 eth1394
alias ieee1394-controller ohci1394
alias char-major-195* nvidia
alias sound-slot-1 snd-via82xx
remove snd-au8830 /sbin/modprobe -r snd-pcm-oss; /sbin/modprobe 
--first-time -r --ignore-remove snd-au8830
install snd-au8830 /sbin/modprobe --first-time --ignore-install 
snd-au8830 && { /sbin/modprobe snd-pcm-oss; /bin/true; }


Here's the output from the /var/log/messages:

If I can help diagnose this further, I'm happy to fiddle. Any clues are 
much appreciated.

Thanks,
