Yes, it sounds to me like you just had too many interupts going on,
running your AGP card at x4 will generate a lot of interupts and running
your USB sounds device at low latency will generate a lot of interupts.
So my guess is that you could have one of these things going flat out but
Do USB devices generate more interrupts per period than PCI? I think all
my machines are running AGP x2 at most.
