I'm not certain about anything right now - I started reproducing this
about an hour ago. It might even be a hardware failure (but I've
tried with different cards of the same type, and all fail, while a

It's a "Thrust" NE2000-clone, based on the RTL8019AS.

And in the relevant header file here line 185 is insw().

Eivind, going back to debugging.
