Re: Interrupt problems on NetBSD/i386 5.0.1

        hello.  I'm a big fan of vmstat -i because it tells me what my current
per-second interrupt load is, and, hopefully, where the interrupts are
going.  If you're having trouble listening to audio and getting disk
timeouts, then I think you're undergoing some kind of interrupt storm which
needs to be resolved.  The question in my mind is, why are you getting so
many interrupts? and who is generating them? and why?  I think that if you
can answer that question, you'll be going a long way toward solving your
problem.  I know it took me a while to figure out the issue that generated
the patch I sent you a couple of weeks ago.
