Does the KDL happen with both cards only or also with only the
Audiophile ?

Could be some IRQ the card doesn't handle as not comming from itself.

A stack crawl at least would help (type bt ENTER)

Also, it seems there is a native Audiophile driver in the sources, you
could probably give it a try (you'll have to add it yourself to the
build, and remove oss_loader or the oss package to make sure they don't
