Or crap hardware. Might not even be the card.

You've got the source code of both the BSD and Linux driver,and you seem
to be one of the few people with the problem so investigate. Start by
looking for stupid things like ethernet cards on IRQ 7/15 with motherboards
generating spurious IRQ's (been there had that one with a board that gave
me spurious IRQ's at the end of each bus mastering DMA transfer) . Check
also you don't have the memory region shadowed or marked for ROM shadowing.
