Hi.

 I get errors like this after a few minutes of traffic on a Sun Neptune 10g
ethernet card. (with nice 500MB/s throughput).

 Then the server seems too busy with something, so it doesn't even respont
to a serial terminal login.

 Any suggestions?

 The system is an Ubuntu Hardy (2.6.24-17-server) amd64.

can you try 2.6.25 or current git?

Also, please always CC: netdev@vger.kernel.org on networking reports.

Yes. It is reproducable under 2.6.25.2, when the load get up.. (worked 
excellent in the <100MB/s range for several hours.

When it works I doesnt seem to be able to get it pass 500MB/s.
