SubjectOops with snd_via82xx and oss-emu on 2.6.0-test1
From
Date

I have a via m10000 with integrated via82xx sound, and I get the
following oops when I play through oss emulation. Alsaplayer seems
to work fine when using alsa directly. (This may also be because
alsaplayer does resampling itself?)

This is with dxs_support=3, without it no oops. But it is necessary,
without it the noise is bad.

The error is easily reproducable, so let me know if any more testing
is needed.
