I once had a similar problem with one of my nics cards.  I was using a 3com
3c509 card and it was trying to grab the same IRQ (10) my sound card was
using. At boot the driver loaded correctly and my system would crash when I
ran ifconfig.  Maybe you are experiencing a similar problem.  Check the IRQ
& IO settings for your cards.  I solved my problem by assigning a different
irq when I loaded the module.

In matters of principle, stand like a rock;
in matters of taste, swim with the current.
