Please try 2.2.14pre16 (at least it's tulip.c). It has some changes
compared to 0.91g which should fix your problems - at least I would be
very glad if you could try it. The problem does not only exists for D21143.

The fix on http://www.suse.cz/development/tulip/ fixes only D21143. And it
still can have a tx-hang.

The change in 2.2.14pre16 tries a more generic way which should work for
other chips, too. It fixes two other bugs, too, by the way.

Stephen R. van den Berg (he posted here) tried to merge both approaches
so that for D21143 the INTR MITIGATION is used (as in
http://www.suse.cz/development/tulip/), otherwise the other one.

He hasn't, though, published a final version of his merge, probably because
he knew nobody who could test it.

So you may mail to Stephen R. van den Berg <srb@cuci.nl> and ask him if
he already has a merge.

Greetings,
