Ok, I've tried both of the following with my reproducer
1. ethtool -K eth0 tso off
RESULT: reproducer causes multiple hosts to be come unresponsive on
first run.
2. ethtool -K eth0 tx off
RESULT: reproducer runs three times without any hosts becoming unresponsive.

Thanks Stephen !
Now some brave fouls to check the 6410 lines of this driver ? ;)
Question of the day : Why TSO is broken in forcedeth ?
Is it generically broken or is it broken for specific NICS ?
Actually, it is only when tx-checksumming is turned off that the problem
doesn't occur (so I'm not sure TSO is the problem).
Additionally, a google also turns up this existing Debian bug
http://bugs.debian.org/506419 which seems to be related.
