I use standalone alsa-driver (kernel one is out of date and doesn't
support au8830 on 64-bit platforms) with gentoo-sources-2.6.14-r5,
gentoo-sources-2.6.15-r1 and gentoo-sources-2.6.15-r4.

Since the output of wavetable daugther card is connected to the "Video" of
analog mixer of AC97 codec, it don't use any resources dma, src or mixer
of au88x0 chip.

Do you have any other error in system log when the driver is loaded ?

Do you have Diamond MX25 (SPDIF) connected to your NX300 ?

Are there any application trying to open hw:0,1 (SPDIF), hw:0,2 or hw:0,3
? 

AFAIK /dev/adsp cannot be mapped to hw:0,1 for au88x0

> Yes, with this patch there is no oops. 

I assume that you mean the oops can be reproduced by 

aplaymidi --port=16:0 any.mid

on your EM64T with alsa-1.0.11rc4 , it is easy for other to test when the
bug can be reproduced by a program in alsa-utils

No, I haven't.

I haven't SPDIF out (at least on rear panel)

> Are there any application trying to open hw:0,1 (SPDIF), hw:0,2 or
hw:0,3 ?

I don't think so. There is only arts running when these errors occur. As I
know in default configuration it use hw:0.0 only.

Yes, It can be easily reproduced. Also without this patch I get about 1250
messages in kernel log like this:
