I hooked an ethernet card which generated link integrity into a non-link  
integrity hub. The resultant errors on the network were causing the  
spurious DMA interrupts. The card worked well enought that I didn't notice  
the errors (busy at the time). If you have starlan hubs
just look for the blinking yellow lights.

What really sucks is when it's a printer that is used sporadically.
This one was a real bummer to figure out, in my case, due to the
fact that the printer was not widely used at the onset of the DMA
problems and so I did not link it to the printer until a month later
when it was getting considerably more use.
