Oops on removing via-rhine [2.4.10-ac11]

[Andrew Over]

Received the following oops when trying to remove via-rhine.

The kernel is 'tainted' by the ALSA modules (no NVdriver!), which
don't yet have the MODULE_LICENSE stuff done.

This occurs with kernel 2.4.10-ac11 (and also 2.4.10-ac8).  System in question is an Athlon 1400 running on a KT266 mobo.

After the oops, via-rhine is reported by lsmod as "(deleted)".

This oops is reasonably easy to reproduce (reinsert and remove
via-rhine enough times and it happens), and any further information is
available upon request.  Next time I reboot, I'll try reproducing the
problem without the ALSA modules.

ksymoops output:
