Answer from Quinton Dolan q (at) OntheNet (dot) com (dot) au:
+---------------------
I am not currently tracking FreeBSD development, but I have a good
idea what may be contributing to the number of timeout errors you are
seeing.
Check around line 730 of if_nv.c (or whatever it's called in 6.0)
sc->linkup = 0;
sc->cur_rx = 0;
sc->pending_rxs = 0;
+ sc->pending_txs = 0;
This should mostly eliminate the problem.
+---------------------
I added this fix which entirely solves the problem in FreeBSD 6.0rc1:
