I'm experiencing similar problems with a 3C996-T under 4.8-REL.
In particular, connecting a 4.8-REL machine to a 5.1-REL machine leads
to some interesting situations: I can do simple pings across the link,
but ssh fails, and heavy pings crash the 4.8 machine. Similarly
changing the interface configuration with ifconfig tends to crash the
4.8 machine (mtu, link0, up/down, etc). The behaviour is somewhat hard
to diagnose, since there's no panic - just a hard lock.
The 4.8-R machine:
$ uname -a
FreeBSD quadric.dsl.isometry.net 4.8-RELEASE FreeBSD 4.8-RELEASE #0: Sun
Apr 6 19:46:37 UTC 2003

$ ifconfig bge0
bge0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500

The 5.1-R machine:

On both machines, the line "bge0: gigabit link up" comes up very
regularly on the console.
I've had the 4.8-R machine talking happily to the (now) 5.1-R machine
running Windows 2000, though also with the "bge0: gigabit link up" messages.
Anything else I can provide to help debug?
