Comment(by corbet):
I'll attach a patch that might fix this. I can't say for sure since I've
never seen it... but it is true that the driver was not really
initializing the hardware at probe time. So, conceivably, anything could
have been going on. This patch resets the hardware at the beginning, and
again whenever it is closed.
There is a vague possibility that it is, in fact, the second audio device
that is interrupting. If so then we'll need to put in something special
to mask that device too, even if it's not configured into the system.
