Hi,
  I have this card in intranet server and I'm very confused about very often
message in log like this:

eth0: Transmit error, Tx status register 82.
  Flags; bus-master 1, dirty 20979238(6) current 20979242(10)
  Transmit list 1f659290 vs. df659260.

  15: @df6592f0  length 8000029a status 0001029a

  We have diskless machines and this is not a good thing, because when this
happens all traffic is stopped, all diskless machines are waiting and users
can't do nothing for several seconds (2-3 seconds). It's not critical, but
it's not comfortable. I tried another card, tried kernels 2.2.16, 2.2.19,
2.4.x series, change cable and still this problem. Any idea what may I do?

  .R.V.
