On my RELENG_8 production box, so far so good.  It usually would hang on
weekend runs, so tomorrow would be a good sign, but not a proof that its
fixed as it has on occasion survived a few weeks in a row.  I am running
the version Jack posted with the one change Sean suggested and is at

http://www.tancsa.com/if_em-8.c

I am also using all default options for the two onboard nics

em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500

options=219b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4,WOL_MAGIC>

em1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500

options=219b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4,WOL_MAGIC>
