[2.3.36pre1] Still problems with es1371/ac97_codec

[2.3.36pre1] Still problems with es1371/ac97_codec

[Ari Pollak]

OK, brief specs: ES1373 chip, running the es1371 driver, on 2.3.36pre1,
with the sound drivers loaded as modules. 
Loading the es1371 module is fine, but as soon as I try to change the
mixer settings with some kind of OSS mixer (aumix, gmix, etc.) I get the
following panic:
