  You are sharing interrupts.  Even if this worked for you it's a bad
idea.  I'd be sure you have the latest bios, and that you've tried the
card in every slot. Also you might have better luck with 2 dual port
cards than a quad port.  (Assuming you have the solts.)  As a last
resort you might try disabling every on board device you aren't using in
the bios.
