No, they're not.  This seems to be the same behavior I reported on this list
some months back. (May 24, to be precise.)

I still haven't found a solution.  AFAICT, it's some bad interaction between
certain motherboards and these cards.  I've pulled working 8139's out of
systems working perfectly, and put them in the systems having trouble, and the
problems remain.

It's definitely driver related, though, and not a hardware problem.  A simple
ifconfig eth0 down; ifconfig eth0 up with invaribly solve the problem, at
least for a few more hours, anyway...
