>Description:
Using FreeBSD 6.1-RELEASE on the new Dell 1950 Dual Core Xeon servers causes the network interface to crash when attempting heavy network usage:

When compiling source from ports mounted on an amd mounted NFS mount the network interfaces will crashes within a few seconds, returning:

bce0: /usr/src/sys/dev/bce/if_bce.c(5003): Watchdog timeout occurred, resetting!

to /var/log/messages
>How-To-Repeat:
Configure amd to auto-mount a directory on a remote machine that contains a ports tree. Create a sybolic link from /usr/ports to the newly mouonted remoted ports tree. `cd` to (for example) /usr/ports/databases/postgresql81-server/ and run `make install`

Within a few seconds all network connections will be lost and the following error will be reported to /var/log/messages:

bce0: /usr/src/sys/dev/bce/if_bce.c(5003): Watchdog timeout occurred, resetting!
