KDB+DDB make interrupt storm on MSI motherboards go away it seems

[Pete French]

I admit I was scepticle of this suggestion - but it actually seems to
have worked. COmpiling a straight GENERIC kernel with KDB and DDB
included do seem to have made my irq22 interrupt storms go away.
Certainly I have spent some time trying to provoke the problem and not
managed to make it read it's ugly head again.

The thing is though, this doen't make me particularly happy - as I am
sure that KDB and DDB are not supposed to make any major changes to
how the kernel functions are they ?
